  1. 입방정 질화붕소 분말을 소결 조제와 혼합하고 이 혼합물을 분쇄 및 탈기 처리한 후 소결시켜 경질 입방정 질화붕소 소결체를 제조함에 있어서, 소결 조제로서 탄화티타늄(TiC), 질화티타늄(TiN), 탄질화티타늄(Ti(C,N) 및 붕화티타늄(TiB2)으로 구성된 군으로부터 선택된 1종의 티타늄 화합물과 니켈(Ni), 몰리브데늄(Mo) 또는 탄화몰리브데늄(Mo2C) 및 질화알루미늄(AlN)의 혼합물을 사용함을 특징으로 하는 방법.
  2. 제1항에 있어서, 소결 조제는 TiX : Ni : Mo 또는 Mo2C : AlN(여기서 X는 C, N, C 및 N, 또는 B2이다)의 혼합 중량비가 (85∼15%) : (10∼50%) : (5∼30%) : (0∼10%)인 것인 방법.
  3. 제1항에 있어서, 소결 조제는 소결 조제 혼합문말과 입방정 질화붕소 분말을 기준으로 하여 약 2 내지 15부피%로 혼합되는 것인 방법.
  4. 제1항에 있어서, 소결 조제는 먼저 습식 분쇄된 다음 건조 분말에 입방정 질화붕소 분말을 투입하고 이를 다시 분쇄하는 것인 방법.
  5. 제1항에 있어서, 분쇄된 입방정 질화붕소/소결 조제의 분말은 질소 분위기 또는 진공하에 탈기처리되는 것인 방법.
