Abstract
A method for making fine powder of a metallic compound coated with ceramics is described. In the method, a gaseous mixture of at least one metal vapor constituting one component of a metallic compound and a carrier gas for the at least one metal vapor is passed at a speed of 50 to 2000 m/second into another element constituting the other element of the metallic compound or in an atmosphere of a gas containing the other element, which is heated to a temperature of not larger than 0.8 time as low as a melting point of the at least one metal so that the metal vapor and another element are reacted with each other while rapidly cooling, thereby obtaining a fine powder of a metallic compound. The metallic compound fine powder is further passed into other metal vapor or other metallic compound vapor to cover the metallic compound fine powder with the film of the other metal or metallic compound.
