PURPOSE: To obtain a briquetted green compact product having a uniform structure by mixing ≥2 kinds of ultrafine particles in a carrier gas, blowing the gaseous mixture on the surface to be coated, and forming the green compact consisting of briquettes of the ultrafine granular particles.
CONSTITUTION: A metal A, for example, is prepared in an ultrafine particle forming chamber 3 on one side, and heated at a specified temp. to form ultrafine particles of the metal. An inert gas is introduced into the metal 0A from a carrier gas introducing pipe 8, and the ultrafine particles are introduced into a mixing chamber 1 from the one side. A metallic oxide B, for example, is simultaneously prepared in an ultrafine particle forming chamber 5 on the other side, and heated at a specified temp. to form ultrafine particles. An inert gas is also introduced into the ultrafine particles from a carrier gas introducing pipe 9, and the ultrafine particles are introduced from the other side into the mixing chamber 1 wherein 2 kinds of the ultrafine particles (a) and (b) are uniformly mixed in a specified ratio by the carrier gas.
