Silicon carbide
Products Description
With quartz sand and petroleum coke as its main raw materials, black silicon carbide is produced at high temperature in an electric resistant furnace. Its hardness is between corundum and synthetic diamond and its mechanical strength is higher than corundum, which makes it an ideal material for high quality abrasivetools.
Application
1. The most widely application of silicon carbide is producing abrasive tools, such as grinding wheels, cutting disks, etc. Black silicon carbide powder also could used as lapping and polishing media.
2. Black silicon carbide is suitable for processing glass, ceramics, stone, metal, rubber and other materials. 3. Black carborundum also can be used as metallurgical additive and high-grade SiC refractory material

- Q: Who knows how many fire heat preservation material are there?
- There are many kinds of fire proof materials. The major material used in construction industry is fire proof and thermal insulation material, mainly include vitrified micro bead insulation board, class A expanded bead fiber board, rock wool board, plastic extruded sheet, polyurethane insulation board
- Q: What type of firebrick does TZ-3 represent?
- Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.
- Q: How long is the fire endurance of Grade A fire resisting shutter
- The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
- Q: Who knows about the fire endurance of sintered shaly hollow bricks?
- Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.
- Q: Which refractory quality inspection authority is good?
- Download refractory quality inspection LIRR in Henan is nationally recognized. Of course, it is an authority, but the cost is very high.
- Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- You can add some hair, sand, yellow mud and some salt, but don’t use cement, it would lead to a thermal explosion.
- Q: What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
- The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.
- Q: What material is used to make furnace pipe of refractory bricks?
- Refractory brick is called refractory?brick for short. It is a kind of refractory material fired by using refractory clay or other refractory materials. Faint yellow or brownish. It is mainly used in building smelting furnace and has resistance to high temperature 1,580 ℃ -1,770 ℃. Also known as refractory?brick. It is refractory material with a certain shape and size. It can be divided into burnt brick, unburned?brick, fused brick (fused cast brick), fire-resistant insulation brick according to preparation technics; It can be divided into standard brick, ordinary brick and special-shaped brick, etc according to shape and size. It can be used as high-temperature building material and structural material of building kiln and all kinds of thermal equipment. It can also withstand a variety of physical and chemical changes and mechanical action under high temperatures. For example, fireclay brick, high alumina brick, silica?brick, magnesia brick, etc.
- Q: how to classify the fireproofing material levels A1 A2 B1?
- their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
- Q: Classification of porosities in refractories and their effects on properties
- The first two types of stomata are commonly examined, known as apparent porosity.
