Correlation of Intergranular Amorphous Structures on Multi-levelled Phase Relationship in Sialon Ceramics: Retrospect and Prospect

Phase diagram in Sialon ceramics and intergranular amorphous films in Si 3 N 4 ceramics, are two successful aspects for fundamental studies in ceramic as an independent discipline. Although differing only in secondary compositions, the small gap in stoichiometry between the two systems divides structure, scale and scope in ceramic research.
