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.5 molar ratio of 0.8 to 1.2; and calcining the mixture of 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.5 molar ratio of 0.8 to 1.2 and a primary particle diameter of 5 to 100 nm. The substance is useful as an antistatic agent, an ultraviolet absorbent, a heat ray absorbent, and a sensor, for example.

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;
- and
- calcining 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.
