Abstract

Abstract: Rod-like α-Sialon crystal particles were obtained by a method of pressure-less sintering and subsequent acid treatments. The reasons for the effect of additives on the morphology of α- Sialon were discussed. The morphology of α-Sialon particles can be controlled with different additives. α-Sialon with light rare earth oxides as additives has α-smaller diameter and a larger aspect ratio than that with heavy rare earth oxides as additives.

Key words: rod-like particles, α-Sialon, nitride ceramics
