Reaction bonded silicon carbide (sisic) ceramic beams have large high temperature bearing, good oxidization-resistance, serving for 4-5 years, about 15 times no longer than alumina without deformation. The products can be used at high temperature, even higher than 1700C for PSSiC Beams. It is applicable to the load-bearing beams in tunnel kiln, shuttle kiln, roller kiln and other industrial kilns. Characteristics: Max temperature tolerance 1380 degree Excellent oxidation and corrosion resistance High thermal conductivity and shock resistance High mechanical strength and abrasion resistance Relevant Recommendation: Silicon Nitride Ceramics Oxide bonded SiC (OSIC) Recrystallizde SiC (Re-SiC) Reaction Bonded SiC (SiSiC)
