First Claim
Patent Images
1. A method of manufacturing titania nanoparticles, comprising:
- (1) a step wherein a salt or alkoxide of titania is mixed with a solvent and scanned with microwaves to synthesize a titania precursor;
(2) a step wherein an alkaline catalyst is added to the solvent and the titania precursor obtained in step (1) to produce spherical nanoparticles of titanium hydroxide;
(3) a step wherein crystalline spherical titania particles are made by-drying and sintering the titanium hydroxide; and
(4) a step wherein the crystalline spherical titania particles obtained in step (3) are hydrophobized.
