Manufacturing method of easy-sintering aluminium oxide
The present invention relates to a method for preparing easy-sintered aluminum oxide, comprising the steps of calcining γ-alumina powder having an average particle size of 50 to 100 ㎛ and a specific surface area of 50 to 100 m^2/g and pulverizing the calcined result. According to the present invention, preparation cost can be reduced by enabling low-temperature sintering, the preparation method is simple, thereby having high reproducibility and enabling mass production, and easy-sintered aluminum oxide having a uniform and dense particle size distribution can be obtained.
본 발명은, 평균입도가 50∼100㎛이고 비표면적이 50∼100 ㎡/g인 γ-알루미나 분말을 소성하는 단계 및 소성된 결과물을 분쇄하는 단계를 포함하는 이소결 산화알루미늄의 제조방법에 관한 것이다. 본 발명에 의하면, 저온 소성이 가능하여 제조비용을 절감할 수 있고, 제조방법이 간단하여 재현성이 높고 대량 생산이 가능하며, 입도 분포가 균일하고 치밀한 이소결 산화알루미늄을 수득할 수 있다.
