Document Type and Number:

Japanese Patent JP6179483

Kind Code:

B2

Abstract:

A composite oxide particle prepared from raw materials comprising: (1) a finely powdered silica having a BET specific surface area of 50 m2/g or greater or an alkoxysilane, and (2) a liquid metal alkoxide other than an alkoxysilane or a nano order metal oxide powder other than finely powdered silica, one of components (1) and (2) being a solid oxide and the other being a liquid alkoxide, wherein the composite oxide particle is prepared by mixing or kneading the raw materials to obtain a sol or gel-like substance, sintering the sol or gel-like substance at a temperature of 300° C. or higher to form a glass-like substance, and then crushing the glass-like substance is provided. Also, a resin composition containing the composite oxide particle, and a reflector for a light-emitting semiconductor device formed using the resin composition are provided. The invention is able to provide a resin composition which is ideal as a reflector material for a light-emitting semiconductor device that exhibits high light reflectance and minimal light transmission, and a composite oxide particle that is added to the resin composition.
