The Science Behind Titanium Anodes in Chlorine Generation

Titanium anodes play a crucial role in the electrolysis process used for chlorine generation in slightly acidic water. These specialized electrodes are designed to withstand the corrosive environment while maintaining optimal performance. The science behind their effectiveness lies in their unique composition and coating technology.

Electrochemical Properties of Titanium Anodes

Titanium anodes are renowned for their exceptional electrochemical properties, making them ideal for chlorine generation in slightly acidic conditions. The base material, titanium, offers excellent corrosion resistance and durability. However, it's the specialized coating that truly enhances its performance. Typically, these anodes are coated with a mixture of metal oxides, such as ruthenium, iridium, or tantalum oxides, which form a stable and highly conductive surface.

This coating, often referred to as Mixed Metal Oxide (MMO), provides several advantages:
