Document Type and Number:
WIPO Patent Application WO/2024/024604
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a highly pure metal composite oxide having excellent thermal conductivity and dielectric characteristics; and a method for efficiently producing said metal composite oxide. Specifically, the present invention is characterized by the use of spinel particles including at least magnesium atoms, aluminum atoms, and oxygen atoms, wherein the quantity of atoms other than said atoms is less than 0.27 at% and/or the number of calcium atoms relative to the sum of the number of magnesium atoms and aluminum atoms is less than 0.02 at%.
