Silicon carbide

Silicon carbide

Extremely hard, refractory material used to form kiln shelves. Highly resistant to corrosive atmospheres, and therefore suitable for salt, soda, and wood firing. Silicon carbide kiln shelves conduct electricity, and should never be used in electric kilns. Occasionally used in powdered form as local reducing agent in oxidation firings.
