Title:
TITANIUM PHOSPHATE POWDER, PRODUCTION METHOD THEREFOR, AND WHITE PIGMENT FOR COSMETICS
Document Type and Number:
WIPO Patent Application WO/2018/180797
Kind Code:
A1
Abstract:
The titanium phosphate powder according to the present invention comprises plate-shaped crystalline particles of titanium phosphate, wherein the plate-shaped crystalline particles have an average thickness of not less than 0.01 μm but less than 0.10 μm, and an aspect ratio obtained by dividing the average primary particle size of the plate-shaped crystalline particles by the average thickness is not less than 5. In the production method for titanium phosphate powder according to the present invention, when titanium phosphate powder comprising plate-shaped crystalline particles of titanium phosphate is produced by reaction of a raw material containing titanium and phosphorus by a hydrothermal synthesis method, a mixture of titanium sulfate and phosphoric acid is used as the raw material.
