    Abstract: A metal-doped molybdenum sulfide powder according to the present invention contains a doping metal in Groups 3 to 13 and molybdenum disulfide having a 3R crystal structure. A first aspect of a method for producing a metal-doped molybdenum sulfide powder includes dry-mixing a powder containing a molybdenum trioxide powder made of an aggregate of primary particles containing molybdenum trioxide, a sulfur source, and a salt of a metal in Groups 3 to 13, and heating the powder at a temperature of 200° C. to 1,000° C. A second aspect includes removing, from a mixture obtained by blending a molybdenum trioxide powder made of an aggregate of primary particles containing molybdenum trioxide, a salt of a metal in Groups 3 to 13, and a dispersion medium, the dispersion medium to obtain a solid, and heating the solid at a temperature of 200° C. to 1,000° C. in the presence of a sulfur source.

    Abstract: α-Alumina in the related art has an average particle diameter of 2 to 20 μm, and it can be said that the α-alumina does not necessarily a large particle diameter. As a result, with respect to the molded product obtained from a resin composition including the α-alumina in the related art as a filler, high heat dissipation characteristics are not obtained, in some cases. An object of the present invention is to provide means of producing α-alumina having a large particle diameter according to a flux method. There is provided a method of producing α-alumina particles including molybdenum which have an average particle diameter of greater than 20 μm, and the production method includes a step of firing an aluminum compound in the presence of a molybdenum compound and a potassium compound.
