The sintered boron carbide ceramic can produce complex shaped products, but often resulting in excessive grain growth and porosity of 3-7Vol.%.The strength and toughness of the material are low (σf<300 MPa，KIC≤3 MPa·m1/2).High density and high mechanical properties for boron carbide ceramic can be obtained by hot pressing sintering technology.

different function of silicon carbide ceramic for different process way
The results show that SiC ceramics with sintered silicon carbide, hot pressing sintering, hot isostatic pressing sintering and reaction bonded silicon carbide ceramic have different properties. For sintered density and flexural strength, SiC ceramics sintered by hot pressing and hot isostatic pressing are relatively more and the reaction bonded SiC is relatively low.
the introduction of process way for our reaction bonded silicon carbide ceramic
The way for making reaction bonded silicon carbide ceramic was first studied in the United States. The process of reaction bonded silicon carbide is as follows: first, the mixture of alpha SiC powder and graphite powder is mixed proportionally, and then the porous body is made by dry pressing, extrusion or slip casting.
