Abstract

PURPOSE: To manufacture needle-form TiO2 having rutile type crystal structure by gradually oxidizing a strongly acidic titanous chloride soln. with an oxidizing gas at a specified temp.
CONSTITUTION: While feeding an oxidizing gas such as air or oxygen into a strongly acidic aqueous soln. of 0.1W4.0M titanous chloride such as TiCl3, the trivalent titanium is gradually oxidized at 50°CWthe b.p. to obtain needle-form TiO2 of 0.3W2.0μm length. This TiO2 enables the crystal orientation of the crystal particles to be controlled, and the electrical properties of sintered porcelain of this TiO2 can be controlled arbitrarily.
