PROCESS FOR PRODUCING FINE PARTICLE OF RUTILE-FORM TITANIUM OXIDE
Document Type and Number:
WIPO Patent Application WO/2007/039953
Kind Code:
A1
Abstract:
A process for producing fine particles of rutile-form titanium oxide which highly protect
against ultraviolet and have high transparency to visible rays. The process
for producing fine rutile-form titanium oxide particles comprises a step (1)
in which titanium dioxide hydrate is treated with at least one basic compound
selected from the group consisting of the hydroxides of alkali metals and the
hydroxides of alkaline earth metals and a step (2) in which the compound obtained
in the step (1) is treated with a carboxylated compound and an inorganic acid.
