Abstract: A manufacturing device includes a first gas inlet that is disposed closer to a first end of a firing furnace and introduces gas into the firing furnace, a gas outlet that is disposed closer to a second end of the firing furnace and discharges gas inside the firing furnace to the outside, and a transport device that transports a metal compound and a flux from a point closer to the gas outlet to a point closer to the first gas inlet. The firing furnace has a heating region, a cooling region, and a reaction region that is defined between the heating region and the cooling region and in which the metal compound and the flux react. The manufacturing device utilizes airflow generated by the gas introduced through the first gas inlet to convert the flux vaporized in the reaction region into powder in the cooling region and to deliver gas containing the powder of the flux to the gas outlet.

Abstract: Alumina is generally used as an inorganic filler, while spinel, which is known to be lower in thermal conductivity than alumina, is used in applications such as gems, fluorescence emitters, catalyst carriers, adsorbents, photocatalysts and heat-resistant insulating materials, but not expected to be used as a thermally conductive inorganic filler. Thus, an object of the invention is to provide spinel particles having excellent thermal conductive properties. The invention relates to a spinel particle including magnesium, aluminum and oxygen atoms and molybdenum and having a [111] plane crystallite diameter of 220 nm or more.
