Abstract
Disclosed is a method for producing a fine powder. Two or more kinds of original materials are suspended and liquefied inert gas to form two or more kinds of slurries wherein each slurry contains at least one or more different kinds of original materials. Granular dry ice grinding medium is put into the slurries. The slurries are individually stirred and the original materials are pulverized into submicron-sized or nano-sized particles in the liquefied inert gas. The slurries are thereafter mixed. The liquefied inert gas is vaporized and the granular dry ice is sublimated. A mixture of the particles of the two or more kinds of original materials is recovered.
