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.

Q:What is the use of refractory?
It is fire-retardant and insulated.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.
Q:Who knows about the fire endurance of A grade fireproofing glass doors?
Fire doors and windows are divided into grade A, B and C according to the real national situation, also the minimum fire endurance has been stipulated, namely, the minimum fire endurance of grade A is 1.50 h, that of grade B and C are 1.00 h and 0.50 h respectively. There are wooden fire doors and steel fire doors. The main purpose of it is to reach the time that fire resistance should last. But door closers are required to install. The fire endurance of A grade wooden fire doors should be no less than 90 min, and that of B grade fire doors should be no less than 60 min, that of C grade fire doors should be no less than 30 min! ! !
Q:What are the characteristics of magnesium fireproof plate
Glass magnesium fire resistance plate is fire proof, water proof, noise insulative, heat perservative, non-toxic and tasteless, corrosion proof, easy for construction, can be sawed and nailed and have a wide range of applications as well as long service life. These advantages allow it to be widely used in construction, decoration, fire protection and be the best material to replace is to replace plywoods, MDF, particleboard, gypsum board. It is a key environmental building materials recommended by national association of construction and decoration. 1 superior fire resistance performance. 2 weather fastness, long service life. 3. light weight and anti-seismic 4 high toughness, good impact resistance and compression resistance. 5 green and environmental 6 economical 7 sound insulative and heat insulative 8 convenient for processing and easy for construction.
Q:What kind of fireproof material is used for steel structure?
Fireproof material means the coating is with thickness 3 mm (including 3 mm) or less, good decorative effect, capable of expanding foam, fire endurance of generally within 2 h of steel structure fire at high temperatures. fire-resistant coating for steel structure is generally solvent-based systems, with strong bond strength, water resistance, weatherproof, good flowing property, decorative; it slowly expanded at high temperature to a dense layer of fire insulation, which has a strong refractory shock, delaying the rise of steel, protecting steel components. ultra-thin intumescent fireproof coatings for steel structure can be used by spraying, brushing or rolling, generally using construction steel with fire endurance within 2 h. new type of ultra-thin fireproof coatings for steel structure has a fire endurance of 2 hours or more, mainly using binding agents of polymethacrylate or epoxy resin and amino resin and chlorinated paraffin, which are of special structure, added with fire retardant system such as high degrees of polymerization, phosphoric acid, dipentaerythritol, adding titanium dioxide, wollastonite and other inorganic refractory materials, solvent oil 200 # solvent composite. All kinds of light steel structure, grid and other use of this type of fire-resistant coating conduct fire protection. As such the fire retardant paint coating is ultra-thin, greatly reducing the amount of thin steel structure fire retardant coating, thereby decreasing the total cost of the project. The steel is protected and the fire is prevented.
Q:What refractories can withstand high temperature above 2100 degrees?
Well, what can you heat to 2100 degrees? ? The dryer? What you used are all substance of low-melting point, which cannot withstand even 1000 degrees. "Is the maximum temperature of refractory bricks 1500 degrees?" Do you mean refractoriness or operating temperature? Firstly, a dryer is impossible to reach 2100 degree. If it does, you might as well use high chrome brick for oxidizing atmosphere. You can use silicon nitride brick for non-oxidizing atmosphere. But I guess it is enough for you to use clay brick, but the price differs a lot! ! !
Q:What are the models of bauxite with high alumina?
China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
Q:Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
ShiLiDe materials are relatively poor, and have nothing to do with 3M at all. 3M is a brand! 3M company is famous for innovation around the world. It has developed a variety of products in a hundred years, involving in automotive, chemicals, telecommunications, construction and other fields. 3M automotive aftermarket has more than 3,000 products (more than 20% of which are high-tech patented products). The world's first explosionproof and heat insulating film, and the first waterproof abrasive paper were born in 3M Company. The abraser, polishing materials, mirror finish of paintwork, the internal and external auto beauty of 3M Company rank the first place in the world. 3M films are divided into conventional films and crystalline auto films. The conventional films of 3M generally have five-layer structure, the base of films is a polyester film which is s plastic film of tearing and puncture resistance. The film is coated with thermal insulation layer, ultraviolet isolation layer, adhesive layer, wear-resistant layer, and protective layer which finally becomes thermal insulation and explosion-proof film with metal sputtering method. Optical micro-attach technology is used in the polyester film which is the base of 3M crystalline auto film. It is coated with more than 240 layers of optical coatings in order to achieve better thermal insulation performance, and be the top anti-explosion and heat-insulating film with clear sight. I hope my answer can help you. Thank you.
Q:what is the common materials for home fireproofing material?
1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof panel, 7.gypsum board Hope to adopt my opinion
Q:how to use boiler fireclay
Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
