摘要： A process of preparing a conductive tin dioxide powder doped with 0.001-2.0 mole % of antimony oxide by heating a mixture of stannous oxalate and an antimony compound, preferably a halide, to form tin dioxide through thermal decomposition of stannous oxalate and accomplish firing of the formed tin dioxide without causing sintering. Preferably the mixture is prepared by using a solution of an antimony halide, followed by evaporation of the solvent. This process gives a tin dioxide powder low in specific resistance for the dopant concentration, high in whiteness and small in particle size.

摘要： The resistivity of an n-type metal oxide semiconductor such as SnO.sub.2, In.sub.2 O.sub.3 or ZnO is lowered by treating the metal oxide with a metal halide such as SnX.sub.2 or SbX.sub.3, in which the oxidation number of the metal is smaller than the largest oxidation number the metal can take, so as to allow the metal oxide to generally uniformly come into contact with the metal halide. The treatment can be done at room temperature by, for example, the use of a solution of the metal halide and does not cause discoloration of the treated metal oxide. This process is applicable also to a conductive material comprising as its essential component at least one n-type metal oxide semiconductor.
