| Description |
A synergistic composition useful for the preparation of dense
neodynium stabilised ß-Si N -á-SiAION composite. The invention 3 4
relates to a synergistic composition useful for the preparation of dense
neodynium stabilised ß-Si N -á-SiAION composite. The composition 3 4
consists of a synergistic mixture of Si N , Al O , AIN, SiO and Nd O . The 3 4 2 3 2 2 3
cost effective synergistic composition is useful for the preparation of
dense neodynium stabilised ß-Si N -á-SiAION composite of the order of 3 4
>98% theoretical density, having high hardness and high fracture
toughness. The dense ß-Si N -á-SiAION composite will be useful for low 3 4
temperature applications as wear parts like bearing and roller materials
and particularly for grinding and milling operations like grinding balls.
