| Destech silicon carbide foam is produced by chemical vapor reaction (CVR), in which high temperature silicon bearing gases convert glassy, or vitreous, carbon foam to SiC. Destech SiC foam has no carbon core unlike SiC foams produced by chemical vapor deposition (CVD). SiC foam has increased density and electrical resistivity over its carbon counterpart, good oxidation resistance (up to 1650°C), good abrasion resistance, and excellent corrosion resistance (slight corrosion in molten bases, e.g. KOH). The properties shown are for solid, fine-grained, SiC. Ash content is less than 0.1%. Used for heating elements, electrodes, nozzles, and cylinders.
