SILICON CARBIDE POWDER, AND PREPARATION METHOD THEREFOR

摘要

A method for preparing a silicon carbide power includes collecting a mixture powder by mixing a carbon source and a silicon source, synthesizing a first silicon carbide powder by heating the mixture powder, forming an agglomerated powder by agglomerating the first silicon carbide powder, and forming a second silicon carbide powder, which has larger particles than the first silicon carbide powder, by heating the agglomerated powder.
