Silicon Carbide/SiC Composition in Minerals & Metallurgy
1.Structure of Silicon Carbide Description
Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.
Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive.
2.Main Features of the Calcined Bauxite
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.
3.Main usage of the Calcined Bauxite
1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials
2.Bonded abrasive tools, lapping and polishing
3.Widely used as a metallurgical additive and refractory material

1). Q: Are you a factory or trading company?
A: We are a factory.
2). Q: Where is your factory located? How can I visit there?
A: Our factory is located in Ningxia, China. You are warmly welcomed to visit us!
3). Q: How can I get some samples?
A: Please contact me for samples
- Q: Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q: What are the materials of insulation firebricks?
- The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
- Q: Who knows the fire rating of fire?partition with steel stud?
- Cement board wall of steel stud: it is used for walls with ceramic in kitchens, restroom, disinfect room, etc. If single-sided tile is made, cement pressure plate can be used on one side. Gypsum board is used on the other side. Fire?rating is A1. CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. 1 hour. It is in line with the fireproof test standard of national building materials. It can reach up to 4 hours at most.
- Q: What's the fire endurance of hollow brick?
- This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. This is the maximum limit.
- Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
- Well, you have no furnace to cast disposable molds. You can sieve sand which is used for blending cement with siever (left the most fine behind)! And then you can go to hardware (parts) factories directly with molds to ask them to pour. Remember that brass (60 copper) needs to be heated to 1200 ℃, while the crucible is not needed.
- Q: Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
- Using high temperature insulation material during casting process .In the molding, assembly the insulation?board on the ingot head or install heat insulation cap . There are three ways to install the molded steel insulation board and install insulation?board on at the head of the ingot, namely, clamping, nail fixation and mosaic technique.Compared with clay-based liner, the use of insulating board will improve high steel billet rate up to about 5% to 10%.
- Q: What is the interior fireproof thermal insulation material?
- polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.
- Q: Who can tell me the properties and classification of insulating refractories?
- Bubble method. This method is the foam agent in a frothing machine mixing with water and prepared uniform fine foam, the foam added in common mud mixing into the foam slurry injection model, together with the drying, demoulding, at 1320 DEG C to 1380 DEG C (high alumina insulating refractory brick for burning) after processing, the plastic products.
- Q: What kind of materials are needed to make refractory bricks?
- Refractory materials generally refer to inorganic non-metallic materials with fire resistance above 1580℃. It plays an important role in metallurgy, nonferrous metals, chemical engineering, ceramics, and industrial production. Different industry needs different materials. You can turn to the knowledgeable internet.
- Q: What are the main materials in concrete fireproofing material?
- it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
