Water dispersion sol of the high refractive index metal oxide fine particles, an organic solvent dispersion sol of the preparation and the metal oxide fine particles

摘要

PROBLEM TO BE SOLVED: To provide a water-dispersed sol containing metal oxide fine particles having a high refractive index and low photocatalytic activity, a method of preparing the same, and an organic solvent-dispersed sol containing the metal oxide fine particles.;SOLUTION: The water-dispersed sol containing metal oxide fine particles having a high refractive index is constituted by coating the surface of specific titanium fine particles having a crystal structure of a rutile type with at least a silica type oxide or a silica type compound oxide. Also provided are its preparation method, and organic solvent-dispersed sol containing the metal oxide fine particles. In addition, the metal oxide fine particles have not only a high refractive index but also low photocatalytic activity.;COPYRIGHT: (C)2010,JPO&INPIT
