Silicon carbide powder, preparation method thereof and preparation method of silicon carbide green body
The invention discloses silicon carbide powder, a preparation method thereof and a preparation method of a silicon carbide green body, belongs to the technical field of silicon carbide and aims to solve the problems of low density and low carbon content of silicon carbide products. The silicon carbide powder comprises two or three of silicon carbide powder with the particle size being 10-15 microns and the purity being larger than or equal to 99.5%, silicon carbide powder with the particle size being 28-35 microns and the purity being larger than or equal to 99.5%, silicon carbide powder with the particle size being 45-50 microns and the purity being larger than or equal to 99.5%, silicon carbide powder with the particle size being 90-110 microns and the purity being larger than or equal to 99.5% and silicon carbide powder with the particle size being 120-135 microns and the purity being larger than or equal to 99.5%. By adopting the silicon carbide powder and the additive manufacturing equipment, a silicon carbide product with high carbon content, high density and low free silicon content can be obtained.
