ABSTRACT:
This invention relates to a process for preparing a titanium oxide powder comprising heating titanium dioxide powder in an atmosphere of ammonia gas at a temperature of about 500.degree. C. to about 950.degree. C. The product powder is very fine, highly uniform in particle size and useful as an electrically conductive material. The powder is colored blue to black depending upon the process conditions and therefore is useful as a pigment, too.
