Title:

ALUMINA-BASED HEAT CONDUCTIVE OXIDE AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2017/047452

Kind Code:

A1

Abstract:

Provided is an alumina-based heat conductive oxide which has not only excellent thermal conductivity but also excellent chemical resistance, water resistance and electrical insulation properties, while having good kneadability (miscibility) into resins, and which is capable of producing a material such as a resin composition having excellent moldability or an article. This alumina-based heat conductive oxide is able to be obtained by firing a starting material mixture that contains an aluminum starting material. The aluminum starting material is at least one substance selected from the group consisting of boehmite, aluminum hydroxide and alumina. The starting material mixture additionally contains at least one other starting material selected from the group consisting of talc, a frit, a boric acid compound, a molybdenum compound, titanium oxide, a magnesium compound, a zinc compound, a zirconium compound, a phosphoric acid compound and a tungsten compound; and the content of the other starting material in the starting material mixture is 0.1-20 parts by mass relative to 100 parts by mass the aluminum starting material.
