A titanium electrode is a sheet of high purity titanium metal. They are 0.5 mm to 1 mm thick. The surface of the electrode is usually black, but can be silver. Titanium Electrodes are stamped with the letters “Ti” for identification.

These devices are used for electrolysis and are primarily applied in the chlor-alkali and water treatment industries. Applications include brine electro-chlorination, electro-decolorization and electro-disinfection.

Titanium electrodes were developed forty years ago. In this time, hundreds of patents have been filed on the technology. However, the commercial use of the technology has been highly secretive. Some of the inventors included Magneto Chemie, ICI and Engelhard.

Magneto Chemie and ICI worked together to develop the titanium-based electrode. The agreement lasted for a number of years. At this time, Magneto Chemie was still a small company. It also helped that International Nickel gave assistance to the company during its formative years.

Titanium-based electrodes are mainly used for electrochemical disinfection. Their performance is largely dependent on the chemical composition and the physical properties of the substrate. This includes the surface roughness, separation and the spatial distribution of features.

As the reaction takes place on the working electrode, the voltage is measured relative to the stable reference electrode. Oxidation currents are constant, suggesting a stable internal electric field.

A titanium electrode is commonly used in the chlor-alkali industry. UTron engineers can custom design a titanium electrode to suit your application.

There is a wide range of applications for a titanium electrode. For example, it is used in electro-chlorination and decolorization of organic pollutants. Another application is the paper wastewater electrochemical treatment.
