In the past, alumina has been widely used as an inorganic filler, and spinel, which is known to have lower thermal conductivity than the aforementioned alumina, has been used in gems, fluorescent light emitters, catalyst carriers, adsorbents, photocatalysts, and heat-resistant insulation materials Use, but did not expect to be used as a thermally conductive inorganic filler. Therefore, this invention aims at providing the spinel particle which is excellent in thermal conductivity.nn n n A spinel particle includes a magnesium atom, an aluminum atom, an oxygen atom, and molybdenum, and a crystal grain diameter of a [111] plane is 220 nm or more. |
