METHOD FOR SEPARATING AND PURIFYING SPINEL TYPE SIALON |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a method for efficiently separating and purifying an amorphous substance coexisting with a cubic spinel type sialon. SOLUTION: In a method for separating and purifying mixed powder of the high-pressure phase spinel type sialon and the amorphous substance manufactured by treatingβ-sialon (chemical formula, Si6-Z AlZ N8-Z , 0<Z<=4.2) with high temperature and high pressure, this method for separating and purifying the spinel type sialon powder is characterized by dissolving and separating the amorphous substance with hydrofluoric acid.
