<p>A sintered ceramic material for high speed machining of heat resistant alloys is provided comprising sialon grains and 0.2-20 <v>/o intergranular phase. At least 80 <v>/o of said sialon phase is beta sialon having a z-value greater than 1.0, but less than 1.5. The ceramic material has a Vickers Hardness HV1 of more than 1530 and it is produced by gas pressure sintering. <IMAGE></p> |
