Patent ID: 8703638

Claim:
A process for producing metal carbonitride mixture particles or metal oxycarbonitride mixture particles, wherein a reaction gas obtained by mixing an organometallic compound or a metal salt of a Group IV or V transition metal, or a mixture of these compounds, with a nitrogen source and optionally a carbon source and an oxygen source as required, and with a diluent gas, is heated to produce carbonitride mixture particles or oxycarbonitride mixture particles of the metal, and wherein the heating involves laser light as a heat source, and wherein the organometallic compound is at least one selected from the group consisting of alkyl metals, metal alkoxides, metal chelates and metal carbonyls, and the metal salt is at least one selected from the group consisting of acetate salts, nitrate salts, sulfate salts, carbonate salts and ammonium carbonate salts.
