Innovation application: Dense Electro Conductive TiO2 Ceramics for Electrode Purposes

Title Dense Electro Conductive TiO2 Ceramics for Electrode Purposes
Abstract

Dense tubular, culindrical or rod type electro conductive TiO2 ceramics are manufactured using extrusion technology with following high-temperature treatment. The obtained products are n-type semiconductors. The developed ceramics can be used for manufacturing of electrodes with high corrosion resistance. The manufacturing technology is developed in semi-industrial scale.
