  • MANUFACTURING METHOD FOR SURFACE-MODIFIED TITANIUM PARTICLES, DISPERSION OF TITANIUM PARTICLES, AND RESIN HAVING TITANIUM PARTICLES DISPERSED THEREIN
    Publication number: 20130164444
    Abstract: A surface-modified titania particle manufacturing method is a method for manufacturing surface-modified titania particles having crystal particles of titanium dioxide and a surface modifier that coats a surface of the crystal particles, including: [1] a first step of preparing a starting solution containing a titanalkoxide compound, an alkoxysilane, an alcohol, an acid, and water; and [2] a second step of performing heating treatment on the starting solution. Furthermore, this method preferably further includes, after the second step, [3] a third step of removing a liquid phase component in the starting solution through evaporation, by reducing a pressure around the starting solution.
