Platinized Titanium & Niobium Anode Dimensionally Stable Anode

Tiaano Customized Platinum plated Anodes or Electrodes are manufactured using the metal of titanium, niobium, tantalum in the production and Pure Platinum Coating. The electrocatalytic functional layers of platinum are used throughout virtually the entire electrochemical industry.

Platinised titanium anodes can only be used successfully in electrolytes which do not attack the titanium base. This excludes use at very low and very high pH values and also Chromium baths containing fluorides.

The service time of the platinised titanium anodes depends on the chemical resistivity of the base metal, the dissolution rate of the deposited platinum in the electrolyte, which in turn depends upon layer morphology, and adhesive qualities, pH, current density and current ripple.

For most applications the dissolution rate is low and the advantages of platinised titanium anodes are far greater than any metal loss. For fluoride-free chromium baths, the platinum consumption will be approximately 1 to 4 g of platinum per million Ah.

Impressed current cathodic protection (ICCP) Platinised anodes have been developed for protection of ship’s hull. Platinised titanium anode are being used in Naval and commercial ships requiring higher current density.

Smooth corrosion-free hulls minimise the power necessary to move ships through the water. Modern vessels, such as the tanker illustrated here in dry dock, are in many cases fitted with impressed current cathodic protection methods for corrosion protection. Platinised titanium counter electrodes used in part of such a system can be seen as four small horizontal strips in line with the propeller shaft.

The principle of impressed current cathodic protection is in connecting an external anode to the material to be protected from corrosion and passing of an external ( impressed ) electrical DC current. These impressed current anodes are also known as dimensionally stable anode or insoluble anodes.

These impressed current anodes are also known as dimensionally stable anode or insoluble anodes. Platinum is an excellent anode material due to its high conductivity and low consumption rate. Due to its high cost, it is not economical to use platinum by itself. So that platinized anodes are produced by electroplating a thin layer of platinum over a lower cost substrate such as titanium, tantalum, niobium or zirconium etc

Tiaano design and manufacturing different dimensions and Shapes of platinum or platinum coated anodes and cathodes for industrial alkaline water plant. The essential components of the ionization chamber are its two collecting electrodes, (the anode and cathode) the anode is positively charged with respect to the cathode. Water Ionizer Electrodes [Anodes or Cathodes] are available with hanging hook, frame or band in the form of sheet, expanded mesh, pipe, wire, rod and custom built.

Why platinum Anodes in Ionization process:

Most good ionizers on the market use electrodes made of platinum plated titanium. Titanium will not dissolve in your ionized water as the cheaper metals like stainless steel does. The ionizer uses grade 1 titanium (as per ASTM Standard) electrodes to be plated with a good electrical conductor. Stainless steel was used for Water Ionizer electrodes in the late 1980's and was found not be a suitable material because they did not last more than a  few years.

Also Increase anode lifetime without sacrificing quality, Maintain predictable and stable electrode position rates, a low consumption rate that conserves precious platinum, Favorable dimensional stability, Corrosion resistance ensures durability with easy maintainability, Light weight.

Tiaano suggest the platinized Titanium anodes and Platinised Titanium Cathode for water alkaline process because of its advantages like no contamination in water, complex shapes is possible, Long lifetime, Easy maintenance, High dimensional stability and loading capacity, Good corrosion resistance, Low weight, Perfect current and distribution. Anodes and cathodes material will be similar. It will be consume  proper equal voltage in all cells.

Platinised Rod titanium and niobium Rod anodes are completely or partially covered with a fee microns of platinum (usually 2.5µm). Where the platinum is consumed after years of use, the underlying titanium or niobium passivates and the bath voltage rises at constant current operation. The base metals are not attacked at the usual operational voltages, in fluoride free chromium baths.

For most applications the platinum wear rate is very low and the corresponding anode life time high. In sulphuric acid chromium baths the platinum consumption is between 1g and 4g platinum per million amp hours. Careful design of the platinised anodes will increase their benefit and maximise their life span.  

Platinised titanium anodes combine the excellent electrochemical characteristics of platinum with the good corrosion qualities of titanium.  This anode is designed for Electro Plating application. They are characterised by the following features and advantages.

•          Energy saving potential

Specifications of Platinized Titanium Anode:-

Platinised Titanium Anodes are exclusively used in the Electro Plating Process. Tiaano Electrodes has the technology to platinum titanium substrates in the form of plate, wire, rod, tube, plate and mesh. Furthermore, we have the ability to manufacture complex fabricated anodes. The external surface of all platinised titanium anodes is essentially pure platinum which exhibits all the normal characteristics of the wrought metal as far as corrosion behaviour is concerned. The secret of the quality of a platinised anode lies in the nature of the interface between the platinum and the titanium. It is well known that normal untreated titanium presents a very inert and intractable surface when it comes to applying precious metal coatings. That this problem was overcome to an adequate extent is demonstrated by the wide acceptance of platinised titanium anodes in different industries throughout the world. Although there are still many platinum electroplated anodes produced without an adequate interlayer, they are used for less demanding applications.

What is Electroplating?

Electroplating involves passing an electric current through a solution called an electrolyte. This is done by dipping two terminals called electrodes into the electrolyte and connecting them into a circuit with a battery or other power supply. The electrodes and electrolyte are made from carefully chosen elements or compounds. When the electricity flows through the circuit they make, the electrolyte splits up and some of the metal atoms it contains are deposited in a thin layer on top of one of the electrodes—it becomes electroplated. All kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum, and lead.

Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which power supply produce electric currents. All these things are examples of electrochemistry: chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products.

Platinized Anodes (Pt. Anode) are produced by plating platinum (Pt) on a specially treated precious metal (Titanium / Niobium) by means of electro deposition process. They are economical as well as it retains the superior physical and chemical properties. There are many advantages as below.

General advantages for Titanium Anode with Platinum Plating or Platinised Titanium Anode:-

1.         Titanium gives corrosion resistance in most electrolytes. Titanium itself will act as a conductor of current without passing current into the electrolyte.

2.         With the application of a thin layer of platinum onto the titanium surface the current will pass along the titanium and enter the electrolyte through the platinum surface with the exposed surfaces of the titanium remaining inactive. The platinized area of the anode will operate at current densities of up to 100 amperes per square ft. of surface area.

3.         The electrical resistance of titanium is high and where solid rods or plates are used it is essential to design with adequate cross sections of titanium and with the shortest current paths to the platinum surface, thus avoiding high volt drops.

4.         Where long lengths of platinized titanium are required to improve the electrical resistance, titanium is formed over copper and the platinum skip-plated onto the titanium. This provides the most economic installation with the best relationship between current density and volt drop.

5.         It is recommended that rectifier 3 phase AC is used and the voltage between anode and electrolyte should be less than 10 volts.

Platinized titanium anodes are suitable for used in impressed current system for jetties, pipelines protected by deep well ground beds, power stations and water storage tanks. Also the major application of Chlorate & perchlorate production, Eectro-chlorination, Electroplating, Sewage treatment, Electro synthesis, Electro Chlorination, Water Treatment, Water Ionization, Waste Water treatment, Sewage Treatment, Effluent Treatment etc…

Titanium anodes are mainly used in the two industrial sectors of electrochemistry and electrometallurgy. Electrolytic industries using metal anodes include: chlor-alkali industry, aluminate production, water electrolysis, hospital Effluent Treatment, sewage treatment, domestic water and food utensils disinfection, industrial water treatment, steel plate galvanized chrome plating, electrodialysis desalination, seawater, batteries Production, cathodic protection, etc. Applications include chemical, metallurgical, water treatment, environmental protection, electroplating, electrolytic organic synthesis and other industries.

Advantages of Platinised Titanium Anode - Application wise:-

It consists of a series of electrodes (plates), each separated by a membrane. The Platinized Titanium Mesh Anode is mostly used, because it has outstanding practical performance, such as strong ability of ionization release, good exchange of electrolyte, close structure and light weight, etc.

Marine Growth Prevention System (MGPS): Platinised Titanium Anode for used to make Marine Growth Prevention System (MGPS). The Marine Growth Prevention System (MGPS) was conceptualized and created with the sole purpose of defeating Marine Growth right at its very root, preventing even the most minute trace of marine organism from depositing itself along the ship’s interior altogether.

Customized Electrode Production with Pure Platinum Plating on Titanium or Niobium

Platinum-titanium insoluble anodes are based on titanium metal as anodes in the form of sheets, plates, rods, filaments, and tubes. The thickness of the standard platinum layer is 2-5µm. Under higher requirements, the thickness of the platinum layer can reach 20µm. The service life of the platinum-plated titanium anode depends on the working medium (electrolyte) and the current strength (current density) of the anode. The current density should not exceed 75A / dm2. Below this value, the wear of the platinum layer is very small, and the service life of the anode can also be estimated. According to experience, the wear of the platinum layer is about 1-4 grams per million amp-hours in a fluorine-free chromium plating solution.

Titanium anode is mainly used in industrial production such as chlor-alkali and sodium hypochlorite, electrolytic synthesis of organic compounds, sewage treatment, seawater desalination, electrolysis of dilute brine, anode for sodium hypochlorite, anode for sodium chloride electrolysis, disinfection of tap water, series of electrode products for sewage treatment, seawater desalination Electrodes, elimination of plankton in industrial circulating water, etc. The main categories are: platinum titanium electrode, titanium electrode, super titanium electrode, noble metal plating electrode group.

The platinized anode is characterized by its three outstanding effects as an electrode material:

1. It is stable, corrosion resistant and can be used in various media.

2. For the oxygen evolution reaction, the over potential is very high

3. For the hydrogen evolution reaction, the over potential is very low.

Ptanode describes the refractory metals, such as titanium and niobium, coated with purest platinum. The electro catalytic functional layers of platinum or various precious metal oxides are used throughout virtually the entire electrochemical industry.

Platinum is a precious metal having good physical and chemical properties such as

Platinum anode is having high corrosion resistance

Platinum anodes are having very good thermal conductivity

Platinum anode is having excellent catalytic nature

Electrochemical process requires anodes. Mainly Platinized Titanium or Platinised Niobium Anodes. Platinised titanium anodes combine the excellent electro chemical characteristics of platinum with the good corrosion qualities of titanium.

Platinised titanium is titanium that has been plated / coated with a very thin layer of platinum, normally by electro deposition process. The purpose of it is to provide a conducting medium that will not react with electrolytes. Platinum is very inert and doesn't readily react electrochemically, so you can do some very good electrochemistry with it. Titanium is used because of its high conductivity and ease in plating under electro deposition process. Furthermore, if the platinum is porous and the titanium is exposed, the titanium will passivate and soon stop interfering with any electrochemistry going on at the electrode.

Titanium - activated by a platinum or a mixed metal oxide (MMO) layer with semiconducting properties - forms an insoluble anode. Both types of anodes are widely used for very different electrochemical applications (electro winning, electro synthesis, electro analysis, electroplating (mainly Automobile parts plating anode, Copper foil plating anode, Hard chrome plating anode, Rotogravure cylinder plating anode, Chromium plating anode, Wire plating anodes, Copper plating anodes, Gold plating anodes, Nickel plating anodes) cathodic corrosion  protection (ICCP) (Mainly seawater and limited space area), disinfection (mainly Electro Seawater Chlorination, Ionization) Gray Water Treatment, Sewage Treatment and waste water treatment, Effluent Treatment and others). The property of titanium to passivate when anodically polarized is the reason for its use as anode base. The activation must be corrosion-resistant against the electrolyte and must remain active.

Tiaano suggest the platinized Titanium anodes for electro Chemical process because of its advantages like complex shapes is possible, Long lifetime, Easy maintenance, High dimensional stability and loading capacity, Good corrosion resistance, Low weight, Perfect current and distribution, Replatinizing with crediting of residual platinum etc…
