The Platinised Titanium electrodes create the ionization, the electrode cell is the heart of an ionizer. 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.
Titanium is non-soluble and stable in water. It will last for many years [20, 30 or more] without corroding. Its durability, strength, and non-toxicity make it the choice of material to doctors and medical scientists use for their implanted medical devices such as artificial joints and pacemakers. Also, because it’s so durable and non-magnetic it makes it the best choice of metal to construct a water ionizer electrode.
Platinum is a catalyst, and is needed to speed up the electrolysis. With the water ionizers changing the water so drastically just by passing the water over the electrodes, the ionization process wouldn’t occur without a speeder-upper.
