Platinized Titanium & Niobium Anode Dimensionally Stable Anode

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

The platinum plated niobium is plated or coated with platinum, which is especially suitable for high-speed and high current density electroplating baths. The niobium has excellent chemical resistance and electrical conductivity. The current that can be carried by a single area is titanium 4 to 5 times, so it is the best choice for high plating of precious metals. The service life is 4-5 times that of platinum titanium, and the bearing current is 4-5 times that of titanium, so the comprehensive performance can save 2.5 times the cost compared with platinum titanium.

Industries used: wheel plating, piston plating, precious metal plating, Automobile parts plating, Copper plating, Hard chrome plating, Rotogravure cylinder plating, Metal recovery, Refining,  Chromium plating, Wire plating, Gold plating, Nickel plating, perchlorate, Bromate, Sodium chlorate,  potassium chlorate etc…
