Influence of Temperature on the Densification and Lattice Parameters of Sialon Ceramic

The sintering behavior and lattice parameters of β-sialon were investigated by varying temperature, z values and the amounts of sintering additive composed of Y2O3. The experimental results indicated that the z value of β-sialon decreases with the sintering temperature increases. The sinterability of the β-sialon declined with the z values increase . As the sintering temperature rise the phenomenon of anti-densification was occurred when the amount of additive was 7wt%.
