  • Processes for making titanium production anodes
    Patent number: 7628937
    Abstract: The present invention relates to processes for making anodes suitable for use in the production of titanium metals. The processes use a kneaded mixture of TiO2 particles, carbon particles, a binder, and a solvent. The mixture is extruded and the solvent is allowed to evaporate to form a green body which is subsequently fired. During firing of the green body, the carbon particles aid in reducing the titanium dioxide to a lower oxide or oxycarbide which can be electrochemically processed into titanium metal.
