Method for preparing boron carbide ceramic composite material based on reaction sintering
The invention relates to a method for preparing boron carbide ceramic composite material based on reaction sintering. The method comprises the following steps: depositing a layer of metallic titanium on the surface of boron carbide powder, mixing the boron carbide powder with carbon black powder, phenolic resin powder and industrial alcohol, carrying out ball milling, drying, granulating to obtain a precursor mixed powder, placing the precursor mixed powder in a die to produce a precursor pressed compact, disposing powdery or blocky silicon on the precursor pressed compact, placing the obtained compact in a vacuum furnace, carrying out silicon infiltration reaction sintering, cooling in a furnace, and removing superfluous silicon on the surface to obtain the boron carbide ceramic composite material. Compared with the prior art, the method has the advantages of simple process steps, effective solving of the problem of high temperature and high pressure sintering needed by routine technologies, low production energy consumption and preparation cost, and very good application prospect.
