The reaction bonded SiC beam is made of silicon carbide powder, graphite powder, mixing additives and organic adhesive substances. the body of the mixture is extruded and then filled in a crucible with silicone powder. Agglomerator in a vacuum heating furnace at 1600 ~ 1800 ° C, fusible silicon powder reacts to silicon in the body, finally, with & beta;-Sic due to heat of reaction.
