The fire resistance and high temperature resistance of silicon carbide is very practical, and has been used more and more widely in daily life. Today, we introduce the corrosion resistance characteristics of silicon carbide radiant tube.
As we all know, the chemical corrosion resistance of silicon carbide products is relatively high, which is mainly due to the high affinity of silicon carbide for oxygen. The reaction between silicon and oxygen in aqueous medium causes passivity. If the silicon oxide products are oxidized, the oxidation can be further prevented. The material migration of the outer layer is only carried out by non-ionic oxidation Even at 1500 ℃, the oxidation resistance of pure silicon carbide is twice as high as that of today's alloys at 1200 ℃.
