PURPOSE:To provide a titanium oxide powder low in electric resistance, excellent in whiteness and suitable for antistatic coatings, etc., by depositing the hydrolysate of a tin compound on the surfaces of titanium dioxide particles and subsequently coating the treated particles with a prescribed amount of a phosphorous compound. CONSTITUTION:The hydrolysate of a tin compound such as tin chloride is uniformly deposited on the surfaces of titanium dioxide particles, and the treated particles are coated with a phosphorous compound such as ortho phosphoric acid in an amount of 0.1-10wt.% based on tin chloride to provide the objective powder. The powder is further preferably thermally treated at 500-800 deg.C in a non-oxidative atmosphere. |
