Abstract:
A process for producing dendritic or asteroidal titanium dioxide micro-particles, which comprises reacting hydrated titanium oxide particles with an alkali, and in one step mixing and reacting the resulting reaction product and an amount of hydrochloric acid in a ratio of 1 to 4 mols of the hydrochloric acid to one mol of the titanium oxide of said reaction product at a speed of at least 2 mols/second under stirring in a reactor to form a dispersion, then aging the dispersion under heating at 85.degree. C. or higher, and then drying and optionally, firing after the drying.
