Abstract

본 발명은 α-시아론 함유 질화규소 소결체 제조방법에 관한 것이다.
본 발명에 의한 방법은, 소결원료 혼합시 용매로써 알콜과 중류수로 이루어진 혼합용매를 사용하여 소결원료중 질화알루미늄(A1N)의 일부를 혼합 단계에서 수화시킴으로써 소결후 상대밀도 99% 이상인 아주 치밀한 소결체를 얻을 수 있는 것이다.
이같이 얻은 소결체는 내 마모성과 고온강도가 우수할 뿐만아니라 파괴인성 역시 우수하다.
본 발명의 방법은 통상의 소결방법인 가압소결법, 상압소결법 및 가스압소결법에 응용할 수가 있다.
본 발명에 의하면 본 발명의 방법을 이용하여 얻은 α-시아론 함유 질화규소 소결체가 또한 제공된다.
