Pure ashes spheroidization method and pure ashes crystals produced thereby

摘要

PURPOSE: A method for spherodizing the pure remains and the pure remains manufactured thereby are provided to manufacture the pure remains with low absorption rate, and to preserve the pure remains without additives in the remains. CONSTITUTION: A method for spherodizing the pure remains includes the following steps: forming pure remains powder by crushing the remains(S110); adding a binder to the powdered remains(S120); molding the remains powder; forming a molded body in which a penetration hole is formed(S130); forming a sintered body by sintering the molded body(S140); and polishing the surface by polishing the sintered body.
