98.5% pure SIC
Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke. Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.

Packing:
- Q: What are some of the new refractories and what are their characteristics?
- Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.
- Q: What are the applications of refractory busway?
- Refractory busway is designed for the power supply in fire-fighting equipment, and it can not be used for other purposes. As the generatrix has good heat resistance, thermal insulation, and the heat of the busway can not be emitted, it can not be used long-term at full capacity. In addition to fire-resistant busway, other bus lines can be operated long-term at full load.
- Q: In entering fire door, which material does well?
- Now generally do stainless steel.
- Q: As for fireproofing material rock wool and glass wool, which one is better?
- First of all, glass wool and rock wool fireproof materials, rock wool and glass wool belong to Class A fireproofing rating, secondly, rock wool can endure high temperature of 800 degrees, glass wool high temperature of 450 degrees, again,unit weight of rock wool is relatively heavier and unit weight of glass wool is lighter, finally, glass wool has better waterproof performance.
- Q: How long is the fire resistance time of the AAAfire resistance rolling shutter door?
- How long is the fire resistance time of the AAA fire resistance rolling shutter door?
- Q: How is the performance of refractory materials?
- It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
- Q: What is the the best matching ratio of refractory cement?
- Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
- Q: What is the mechanism of the errosion of the iron to the refractories?
- For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.
- Q: Is there a worker in (Jigang refractory plant)?
- Units in this way, it is necessary to slowly boil it, wages will come up. You are a labor worker, and can not share with the stock system staff. There's a difference between salary and vacation.
