Composite nitride sintered body |
摘要 |
A composite nitride sintered body consisting essentially of aluminum nitride, boron nitride and at least one metal compound selected from the group consisting of compounds of metals of Groups IIa and IIIa of the periodic table. The composite nitride sintered body is produced by intimately mixing a powder of aluminum nitride, a powder of boron nitride and at least one metal compound selected from the group consisting of metal compounds of metals of Groups IIa and IIIa of the periodic table, and sintering the mixture under atmospheric or elevated pressures at a temperature in the range of 1600 DEG to 2400 DEG C. The sintered body has a good machinability.
