Abstract: The purpose/problem of the present invention is to provide a method for producing tungsten complex oxide particles useful as a heat shield material or the like that permits inexpensive production of a stable composition. This method for producing tungsten complex oxide particles includes a step for preparing a dispersion in which a raw material powder has been dispersed, a step for feeding the dispersion into a thermal plasma flame, and a step for supplying gas containing oxygen to the terminal portion of the thermal plasma flame and producing tungsten complex oxide particles. The dispersion preferably includes a carbon element.

Abstract: Provided are: composite particles having excellent oxidation resistance; and a method for producing composite particles. The composite particles are obtained by forming a composite of TiN and at least one of Al, Cr, and Nb. In the method for producing composite particles, a titanium powder and a powder of at least one of Al, Cr, and Nb are used as raw material powders and composite particles are produced using a gas phase method.

Abstract: Provided are: composite particles having excellent oxidation resistance; and a method for producing composite particles. The composite particles are obtained by forming a composite of TiC and at least one of Zr and Si. In the method for producing composite particles, a titanium oxide powder and at least one of a zirconium oxide powder and a silicon oxide powder are used as raw material powders, and composite particles are produced using a gas phase method.
