Summary:PCT No. PCT/JP87/00592 Sec. 371 Date May 19, 1988 Sec. 102(e) Date May 19, 1988 PCT Filed Aug. 7, 1987 PCT Pub. No. WO88/00934 PCT Pub. Date Feb. 11, 1988.The present invention relates to a high-strength BN single sinter or a high-strength composite sinter consisting of BN and other ceramics, and a process for its production. The present invention is characterized in that an amorphous BN powder or a powder capable of producing armorphous BN in the course of the sintering step is used as a part or whole of a starting material for a BN component. A boron nitride sinter obtained according to the present invention can be effectively utilized, for instance, as an electronic component part.
