1. Product Description
Refractory silicon carbide plate, 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 plate 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. Feature of Product
1) Good properties of cauterization-resistance
2) Anti-oxygenation,anti-aging,anti-transfiguration
3) Heat-resistance and big intensity at high temperature
4) Perfect heat-conduction performance and wearability hi
