METHOD FOR HOMOGENIZING FINE POWDER

摘要

PROBLEM TO BE SOLVED: To provide a method for homogenizing fine powder which can disperse the fine powder uniformly by a simple operation even when the powder contains cohesive and adhesive substances. SOLUTION: The fine powder is charged in a dispersion medium of a suspension in which the solid particles of a liquefied gas the freezing point of which is higher than the boiling point of a liquefied inert gas are dispersed in the liquefied inert gas. After the powder and the dispersion medium are agitated to disperse or mix them enough, the medium is evaporated.
