COATED POWDER SOLID AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a solid of coated powder, at the time of sticking powder having certain characteristics with one another and forming a compacted body, capable of giving a desired arrangement to the powder grains with one other or capable of arranging them to a position at which a prescribed interval in which objective characteristics appear can be given. SOLUTION: Powders each having a coating film with uniform thickness of 0.01 to 20μm on a surface or powders each having plural layers of coating film in which at least an adjacent coating film is made of different kinds and having uniform thickness of 0.01 to 5μm per layer are mutually stuck by the coating films, or they are mutually stuck by an adhesive, by which the powders each having the coating film are mutually stuck.
