Conventionally, spinel is suitable for gemstones, catalyst supports, adsorbents, photocatalysts, optical materials, heat-resistant insulating materials, etc., but its use as an inorganic filler having thermal conductivity has not been conceived. Therefore, an object of the present invention is to provide spinel particles excellent in thermal conductivity. A kind of spinel particle, it comprises spinel and molybdenum, and described spinel contains magnesium atom, aluminum atom and oxygen atom, and described molybdenum is arranged on the surface and/or inside of aforementioned spinel, and the aforementioned spinel The crystallite diameter of the [311] plane is 100 nm or more. |
