EFFECT OF DIFFERENT NUCLEATION TEMPERATURES ON THE GRAIN MORPHOLOGY OF ALPHA-SiAlON CERAMICS

Nitrogen-rich yttrium-cerium-containing multi-cation alpha-SiAlON starting compositions were prepared by gas pressure sintering using conventional alpha-Si3N4 powder. Microstructural characterisation of the two stage sintered materials showed elongated alpha-SiAlON grains in various conditions. The...
