RSiC(recrystallized silicon carbide) batts usually as kiln shelves for high purity Alumina ceramics kiln, it has more advantages than other SiC plate, but sometime R-SiC slab will appear little white & transparent material, then adhesive alumina ceramics, that’s a serious problem, you know what’s material of this ReSiC plates emission? Now Sndou tell you: normally technical ceramic require oxygen atmosphere in the kiln, when firing temperature up to 1600C, smaller quantity Si in Re-SiC plate will reaction with O2, then Si+O2=SiO2, 1600C make silicon dioxide evaporated, then enclosed alumina ceramic products.
Generally do coating on RSiC kiln shelf surface, or put high purity Zirconia sand or corundum sand for avoid directly touch. Tangshan Sndou SiC Ceramics Co.,Ltd could offer full solution on your SiC kiln furniture of technical ceramics, Electronic ceramics, Semi-conductor, CVD-SiC, higher accurency machining process.
