Loading bate temperature (HWS) it is to show material issues bate or metabolic temperature in certain load. The fireproof data that seeks loading bate temperature to be as high as 2000 ℃ may have some of challenge, because common fireproof material is in great majority,this kind of high temperature falls to metropolis experience is out of shape significantly or fuse.
However, in special industrial application, may a few high quality fireproof material can hold relatively stable property below very high temperature. These material may include alumina, carborundum, nitrogen to change silicon to wait. But, these material can be used at the harsh environment such as spout of motor of special high temperature furnace, rocket normally, and its price may be very high.
Carborundum: Carborundum is one kind is had exceedingly good electricity, heat, mechanistic the material with chemistry. It is high temperature resistant, can work steadily for a long time in high temperature environment, bear the high temperature that is as high as 2700 ℃ . Carborundum still has the characteristic such as tall thermal conductivity, corrosion resistance, high strenth and tall tigidity. Because these are characteristic, carborundum is mixed in material of parts of an apparatus of power electronic parts, photoelectron, pottery and porcelain, abrasive the domain such as sharpener and car and aerospace industry has wide application.
Nitrogen changes silicon: Nitrogen changes silicon is a kind of white farinaceous crystal, have the character such as high melting point, tall hardness. It is applied extensively on industry, if be used at high temperature as material of project pottery and porcelain,light the component such as engine of gas turbine, aircraft, heat exchanger. Nitrogen changes silicon to still can serve as material of heat-resisting coating, insulating material, mechanical wear-resisting and cutting tool to wait. In addition, because nitrogen changes silicon pottery and porcelain to have,good insulating property is mixed be able to bear or endure urgent cold urgent hot sex, it also is used at making the part such as glow plug.
Zirconia: Zirconia is solid of a kind of white, have high melting point, high boiling point, high refractive index and the characteristic such as tall electric thermal conductivity. In chemical reaction, zirconia shows intense oxidation reproducibility to pledge, can by reductive be low condition or be oxidized to be costly condition, this makes the effect that it has activator in a lot of chemical reaction. In addition, zirconia still has good thermal stability and corrosion resistance, because this is in,the domain such as pottery and porcelain, electron, medical treatment is having wide application.
Should find the loading bate temperature that accords with your demand the fireproof material of 2000 ℃ , you may need to farther major seeks advice and be investigated, whether to have feasible solution in order to decide, and the budget that whether accords with you and performance demand.
