#4: Disadvantages of Platinized Titanium Anodes

As a substrate for platinized anodes, titanium has the disadvantage of lower electrical conductivity compared to niobium or copper. A low breakdown voltage also is an important limitation for applications that involve a chloride medium. A lower operating voltage of 8 volts reduces the current density. Platinum on titanium substrate anodes are used in applications where lower electrical conductivity and breakdown potential are not a concern. For better electrical conductivity, copper-cored platinized titanium anodes are sometimes used.

Applications for platinized titanium anodes are limited to those electrolytes that do not react with titanium. They cannot be used in chromium baths that contain fluorides.
