ABSTRACT:
A process for producing an electrically conductive mixed oxide comprises sintering a power mixture comprising from 30 to 98% by weight of titanium oxide, in terms of the amount of titanium based on the total amount of all the metallic elements, from 1 to 10% by weight of at least one of titanium metal and titanium hydride, in terms of the amount of titanium based on the total amount of all the metallic elements, and from 1 to 60% by weight of at least one of tantalum oxide and niobium oxide, in terms of the amount of tantalum, niobium, or tantalum and niobium based on the total amount of all of the metallic elements. The process provides a sintered solid comprising titanium, at least one of tantalum and niobium, and a stoichiometrically deficient amount of oxygen. The content of titanium in the sintered solid is from 40 to 99% by weight and the content of tantalum, niobium, or tantalum and niobium in the sintered solid is from 1 to 60% by weight, respectively, based on the total amount of all of the metallic elements in the mixed oxide.
