1. Description
Silicon carbide kiln post is combined with high purity silicon carbide and ultra fines. Shaped by vibration, made by high sintering. The SiC kiln post is oxide bonded silicon carbide based products, which is used in Kiln Furniture. It is featured with high bending strength at elevated temperature, good abrasion resistance, Resistance to thermal shock, high thermal conductivity and offers a good life.
Refractory silicon carbide kiln post is distinguished by high strength that stays nearly constant up to very high temperatures (1500° C), maintaining that strength over long periods.
This material displays an extremely high corrosion resistance in acidic and basic media, and this too is maintained up to very high temperatures. These properties are outstanding among high-temperature ceramics, and are complemented by high thermal shock resistance, high thermal conductivity, high resistance to wear, and hardness close to that of diamond.
