    Method for Preparing Silicon Nitride Sintered Body and The Silicon Nitride Sintered Body Prepared by The Same

    본 발명은 질화규소 분말과 산화물계 소결 조제를 혼합한 원료분말을 열처리하는 단계; 및 상기 열처리하는 단계를 거친 결과물을 소결하는 단계;를 포함하고, 상기 열처리하는 단계를 거친 결과물은 α-질화규소 70 내지 90 중량부 및 β-질화규소 10 내지 30 중량부를 포함하는 것인 질화규소 소결체의 제조방법 및 이에 따라 제조된 질화규소 소결체에 관한 것이다.

    The present invention relates to a method for preparing a silicon nitride sintered body, and a silicon nitride sintered body prepared thereby, the method comprising the steps of: thermally treating raw material powder in which silicon nitride powder and an oxide-based sintering aid are mixed; and sintering a product formed by passing through the thermal-treatment step, wherein the product formed by passing through the thermal-treatment step comprises 70 to 90 parts by weight of α-silicon nitride and 10 to 30 parts by weight of β-silicon nitride.
