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.
