Ceramic kiln used refractory Silicon carbide kiln shelves
310*310*10mm
1. Introduction
Refractory silicon carbide kiln shelves, also known as carborundum,
is a compound of silicon and carbon with a chemical formula SiC. is
made through high temperature sintering, adopting the higher
quality raw materials. It has characteristics of stable
performance, excellent thermal shock resistance, oxidation
resistance, long life, thin volume but high bulk density. Its good
thermal conductivity can assure to save energy at maximum level.
Refractory silicon carbide kiln shelves 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.
2. Features
1). High temperature resistance
2). Corrosion resistance
3). Oxidation resistance.
4). Wear resistance.
Silicon carbide kiln shelves have the characteristics of high
flexing strength at elevated temperatures, high thermal shock
resistance. High corrosion resistance and high thermal
conductivity, high resistivity against alkalis.
