    The present invention relates to a manufacturing method of a spherical aluminum oxide powder, which includes the steps of: flame spraying an α-alumina powder and collecting a spherical aluminum oxide powder; washing the collected spherical aluminum oxide powder until the electrical conductivity of a supernatant is in the range of 80 to 300 ㎲/cm; and drying the washed spherical aluminum oxide powder. According to the present invention, when forming a resin composition using the spherical aluminum oxide powder, the viscosity and fluidity can be improved and bonding strength with a resin can be improved.

    본 발명은, α-알루미나 분말을 화염 용사하고 구상 산화알루미늄 분말을 포집하는 단계와, 상등액의 전기전도도가 80∼300㎲/cm 범위가 될 때까지 포집된 구상 산화알루미늄 분말을 세척하는 단계 및 세척된 구상 산화알루미늄 분말을 건조하는 단계를 포함하는 구상 산화알루미늄 분말의 제조방법에 관한 것이다. 본 발명에 의하면, 구상 산화알루미늄 분말을 이용한 수지 조성물 형성시에 점도 및 유동성이 개선되고 수지와의 결합력이 좋아질 수 있다.
