Abstract

The present invention relates to a synergistic composition for the preparation of dense Samarium stabilised alpha-SiAlON by inventive steps of selecting compositions from the system Si N - Al O .AlN - 3 4 2 3 Sm O .9AlN - SiO resulting into dense product of the order of > 98% 2 3 2 theoretical density with the advantages such as cost effectiveness, high hardness and high fracture toughness. The produced dense alpha- SiAlON will be useful for low temperature applications as wear parts like bearing and roller materials and particularly for grinding and milling operations like grinding balls.
