METHOD FOR PRODUCING BORON CARBIDE-SILICON CARBIDE-SILICON COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a composite material excellent in grindability regardless of the composite material with high specific rigidity utilizing the high specific rigidity of boron carbide.

SOLUTION: The method for producing the composite material whose main ingredient is boron carbide-silicon carbide-silicon comprises a forming step to produce a formed body having a filling ratio of 60-80% by forming a raw material whose main ingredient is boron carbide-silicon carbide-carbon source and a reaction sintering step to convert carbon to silicon carbide by impregnating the formed body with molten silicon.
