Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree.

Aplications :
Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. 

The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc.

Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

Q:what is the grading standards of external wall thermal insulation materials?
external wall thermal insulation materials are divided according to Fire rating: 1, the combustion performance of insulation materials rates A. inorganic fiber spray coating, glass wool, foam glass, foamed ceramic , rock wool, foam cement, obturator perlite 2, the combustion performance of insulation materials rates B1: Extruded polystyrene board (XPS)after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polyphenyl granule.3, combustion performance of insulation material rates B2. Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
From the perspective of appearances, grade A is 70mm, B 50mm. Their materials are the same .
Q:Which brand of refractory fiber hard thermal insulation board is better?
One colleague said Huayou refractory fiber hard thermal insulation board is good. The size (mm): 600*400*60. refractory temperature: 1770 ~ 2000 ℃ (℃), and the price is 2850 yuan a ton.
Q:What's meaning of CN of fire-resistant material?
The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
Q:What is refractory?
Refractory is an inorganic nonmetallic material with minimum refractoriness of 1580 ℃. Now, refractory is not defined merely by judging that whether its refractoriness is at above 1580 ℃. Currently, refractory, an inorganic nonmetallic material, are widely used in metallurgy, ceramics, power and other industrial fields.
Q:The effect of a high content of water in liquid resin exerted on refractory material?
For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
Q:How do refractory materials apply into pyrophyllite?
Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
Q:What are the models of refractory cables?
NH is the firat letter of "refractory" in Chinese phonetic alphabet; It is V, not W. PVC insulation and sheath; K in KVV represents the control cable. 5 * 10 represents the cable is made up of 5 core cables whose nominal cross section is 10 square milimeter.
Q:Can anyone tell me the requirements of the refractory masonry??
Kaolin is mainly composed of kaolinite crowded minerals that is in the shpe of tiny flake which is less than two microns, tube and folding flake. The kaolinite crowded mineral consists of kaolinite, dickite, pearl stone, halloysite, etc. and its ideal chemical formula is AL2O3-2SiO2-2H2O. The main mineral component of it is kaolinite and halloysite.In addition to the kaolinite crowded mineral, kaolin is accompanied by other minerals like montmorillonite, illite, pyrophyllite, quartz and feldspar. The chemical composition of kaolin contains large amounts of AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and traces of K2O, Na2O, CaO and MgO, etc. The white pottery is made of kaolin. At present, the internationally accepted scientific name for kaolin is Kaolin which is derived from the kaolin mountain in the eastern suburb of kaolin village in Jingdezhen.Such special properties of kaolin as its plasticity,cohesiveness, certain dry strength, sinterability and firing whiteness make it the main raw material for ceramic production; properties like whiteness, softness, high dispersibility, and adsorbability allows it to be widely used the paper industry. In addition, the kaolin is also widely used in some industrial sectors such as rubber, plastics, refractories, oil refining as well as agriculture sector and cutting-edge technology for national defense. According to the purpose and requirements, kaolin can be processed and purified and it can be used to manufacture activated clay.
Q:What is special refractories?
Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
