Silicon carbide │ Technical ceramics

In this scenario, the advantage is that silicon carbide is resistant to almost all acid and alkali mixtures – even at high process temperatures. That’s why SiC components are also suitable for separating corrosive vapours from carrier gases or for condensing corrosive vapours – in general it can be used with all media that’s sensitive to contact with metallic surfaces.

Silicon Carbide Powders | McMaster-Carr

Silicon carbide is nearly chemically inert, meaning it won’t corrode in chemical processing environments. It’s good for use in rubbing parts such as bearings and bushings because it dissipates heat well and doesn’t warp from temperature swings. Mullite, however, is often preferred for these appliions.
