Abstract:
A method of producing electroconductive anhydrous zinc antimonate, comprising the steps of:mixing a zinc compound and a colloidal antimony oxide in a ZnO/Sb.sub.2 O.sub.3 molar ratio of 0.8 to 1.2; andcalcining the mixture at 300 to 680.degree. C. in a gas containing steam to produce an electroconductive anhydrous zinc antimonate having a ZnO/Sb.sub.2 O.sub.3 molar ratio of 0.8 to 1.2 and a primary particle diameter of 5 to 100 nm,wherein a partial pressure ratio water vapor to the gas in the gas containing steam is 0.10 to 1.0.
