B4C-HfB2-SiC ternary high-temperature eutectic composite ceramic material and preparation method
The invention discloses a B4C-HfB2-SiC ternary high-temperature eutectic composite ceramic material. According to the composite ceramic, through changing the ratio of boron carbide, hafnium boride and silicon carbide, the ceramic has a uniformly distributed eutectic structure. A variation range of B4C molar content is 35-55%, a variation range of HfB2 molar content is 10-45%, and a variation range of SiC molar content is 25-50%. According to the invention, the B4C-HfB2-SiC composite ceramic material prepared with an arc melting method has excellent characteristics of eutectic in-situ ceramic, and has performance advantages of HfB2, SiC and B4C. The material can be used as a precision machining tool material and an ultra-high-temperature ceramic material. The material can be widely applied.
