Abstract

The present invention relates to a process of making dense Samarium stabilised á-SiAlON by inventive steps of using compositions from the system Si N -Al O .AlN-Sm O .9AlN-SiO resulting into dense 3 4 2 3 2 3 2 product of the order of > 98% 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.
