METHOD FOR PREPARING SILICON CARBIDE POWDER
본 발명의 한 실시예에 따른 탄화규소 분말 제조 방법은 베타상의 탄화규소 분말에 시드를 첨가하는 단계, 그리고 상기 베타상의 탄화규소 분말을 열처리하여 알파상의 탄화규소 분말을 형성하는 단계를 포함한다.
A silicon carbide powder includes at least one group selected from a first group comprising an alpha phase silicon carbide pulverulent body of which a granule size (D50) is greater than 0 μm and less than 45 μm with impurities less than 10 ppm, a second group comprising an alpha phase silicon carbide pulverulent body of which a granule size is greater than 45 μm and less than 75 μm with impurities less than 10 ppm, and a third group comprising an alpha phase silicon carbide pulverulent body of which a granule size is greater than 75 μm and less than 110 μm with impurities less than 10 ppm. In addition, a method for preparing a silicon carbide powder includes adding seeds to a beta silicon carbide powder, and forming an alpha silicon carbide powder by heat treating the beta silicon carbide powder.
