Sialon is an excellent material belonging to the oxynitride ceramics. It has high strength, wear resistance, and other mechanical and chemical properties.   β–sialon has the general formula of Si6-ZAlZOZN8-z,where z=0  to 2.1. In the present work in total nine different Sialon samples with different compositions were sintered at 7 different temperatures viz., 1575 to 1840oC. Green density, fired density, % linear shrinkage at different temperatures and compositions were reported. Theoretical density of 3.2 gm/cc. was almost reached. The properties were compared and various parameters were corroborated In terms of at% N.
