Product Description
1. Description
Black silicon carbide is produced at high temperature in an electric resistance type furnace with
quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina
and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is sharp and
has electrical and heat conductivity in some degree.
2. Application
As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand
tiles etc.
As the metallurgical deoxidizer and high temperature material.
Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and
metallurgical materials.
High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers.
Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high
temperature resistant to oxidation.

- Q:What are the types of refractory sealant?
- 1. The characters of sealant for construction According to the characters, sealant for buildings are classified into caulk, sealants and construction sealant in China; They are named in accordance with the function and different basepolymeters. In the relevant standard for products,
- Q:What are the applications of refractory?
- Refractory usually refers to the inorganic non-metallic material, whose refractoriness is above 1580℃. And it can be used for necessary parts. You can search more information on the Internet. It can be used in ferrous metal metallurgy, chemical, ceramics and so on. Fire material generally refers to above 1580 ℃ refractoriness of inorganic material, where the material can be used in corrosion, the network is very strong look, we know that colored when the metallurgical, chemical-resistant ceramics, etc. of industrial production high temperature. Different things are needed in different industries.
- Q:Who knows about the grade C fireproof door materials?
- I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.
- Q:How to divide fire resistant level of fire door?
- Fire resistant level of fire door【Class A fire door】. Class A fire door is also called complete fire door. It can meet the requirement of fireproof thermal insulation and refractory integrity at the same time in specified time. Fire resistant levels are 0.5h(Grade C), 1.0h(Grade B), 1.5h(Grade A) and 2.0h, 3.0h. 【Class B fire door】Class B fire door is also called part heat insulation fireproof door. Its requirement of fireproof and thermal insulation performance is 0.5h. Refractory integrity levels are 1.0h, 1.5h, 2.0h and 3.0h respectively. 【Class C fire door】Class C fire door is also called not thermal insulation fireproof door. Ther is no requirement of its fire resistance and thermal insulation. It only meets the requirement of refractory integrity in specified refractory time. The grading of refractory integrity is 1.0h, 1.5h, 2.0h and 3.0h respectively. There is the content of not thermal insulation fire door in British BS standard.
- Q:who knows the technology of fireproofing material?
- 1, Foam insulation board,it's the foam insulation board material made by inorganic ceramic material through high temperature roasting, and is called for short as ceramic insulation plate. 2, composite cement foaming insulation board is made by cement,fly-ash,silica fume and other main materials and it's a kind of hole-closed?lightweight hydrophobic insulation board made by the technologies of foam,maintenance,cutting processing. 3, gypsum foam thermal insulation board is inorganic thermal insulation board that takes industrial by-product gypsum as the main raw material, modify the gypsum through physic modified principle, then foam, casting and cutting through chemical foam principle. 4, aerated concrete panel is made by lightweight material,silicious material, foaming?agent and other raw materials and it's a kind of lightweight concrete plate material made by the high pressure steam of manufacturing technique. 5, rock wool board is made by natural igneous rock and other main materials, and it's a kind of plate with thermosetting resin as binder made through melting in high temperature and centrifugation.
- Q:What 's the highest temperature can magnesium plate glass resist ?
- Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature.
- Q:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
- Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material. If it is glass fireproof door, then the door frame should be equipped with fire-proof materials. I know a exclusive shop in Beijing dealing with fireproof doors, called Naecame.
- Q:What are the materials used in refractory material processing?
- AZS special refractory brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on. Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
- Q:What is the classification standard of fireproofing material levels?
- the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. class B1: combustible?building?materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F
- Q:In entering fire door, which material does well?
- Hello: The basic material has steel, wood, or steel. The fireproof sandwich board, such as rock wool and perlite. The material of fire door, fire door has steel fire door and wooden fire door. There is no doubt that wooden fire door can't be used as entering door. In the steel fire door, two layers of steel plate in the clip is flame retardant material. In general, there is no lock. Of course, you can add locks in it, but it doesn't have pry proof function. I hope my answer can help you.
