THERMALLY CONDUCTIVE COMPLEX OXIDE, PRODUCTION METHOD THEREFOR, THERMALLY CONDUCTIVE COMPLEX OXIDE-CONTAINING COMPOSITION, AND USE THEREFOR
An object of the present invention is to provide a thermally conductive composite oxide that can realize physical properties required for coating films, films, and molded products obtained by single use of the thermally conductive composite oxide blended into paints and resin compositions without the need for an improvement measure such as surface treatment and that is excellent in thermal conductivity, water resistance, acid resistance, and electric insulation. The object is achieved by a thermally conductive composite oxide and the production process thereof, the thermally conductive composite oxide being a composite oxide having a spinel structure and containing aluminum as a main component metal and at least one metal other than aluminum, and in the thermally conductive composite oxide, the metal other than aluminum is at least one selected from the group consisting of magnesium, zinc, calcium, and strontium, the ratio, (b mol)/(a mol), of the number of moles (b) of the metal other than aluminum to the number of moles (a) of an aluminum element in the alumina-based compound is 0.1 or more and 1.0 or less, and the Mohs hardness of the thermally conductive composite oxide is less than 9.
