Corundum Ceramics Products

Application:

It is suitable for all kinds of electrical heating fittings, thermal protection pipe, crucible and so on. The main products include :99% corundum tube ,95% corundum tube ,85% high alumina tube ,99 corundum crucible, etc.

Properties:

Corundum ceramic product is a kind of ceramic material with alumina (Al2o3) as the main body. The ceramic dielectric constant is low, the insulation strength is high, the volume resistivity is high, the resistance to change strength is good.

●Good temperature resistance, long-term use temperature 1600℃, short-term use temperature `1800℃

●Good resistance to cold and heat, not easy to crack.

●High grouting density.

Si3N4+SiC Products

Application:

Widely used in heater,thermocouple protection tube and so on.

Properties:

Silicon nitride combined with silicon carbide protective tube is made of high purity silicon carbide powder and metal silicon powder after porous billet is sintered at 1400℃~1500℃ temperature. The pure nitrogen gas is flushed into the furnace during the sintering process, so that the silicon in the billet reacts with nitrogen to form Si3N4, Therefore, nitrogen silicon combined with silicon carbide is a two- phase composite, in which SiC accounts for about 60%, Si3N4 about 37%, and the operating temperature is about 1500℃.

Hard texture, Morse hardness is about 9, belong to high hardness material, second only to diamond. The strength and hardness of 1200℃~1400℃ at high temperature are almost the same as that of normal temperature. With the different temperature, the maximum safe use temperature can reach 1650℃~1750℃. Small thermal expansion coefficient, high thermal power rate, good thermal shock stability, corrosion resistance, oxidation resistance.
