Applications
1.metallurgical deoxidizer
2.high temperature resistant materials
3.as abrasive, abrasive tools can be used to such as grinding wheels, whetstones, grinding head, sand tile etc
Advantages
1. corrosion resistance, high strength, high hardness,
2.good wear-resisting performance,resist to shock
3.stable chemical performance, high thermal conductivity, high resistant temperature
Product Description
Silicon carbide is a man-made material manufactured through heating silica sand and carbon to high temperatures in the Acheson furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9.25), is chemically inert and does not melt. Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high temperatures. Silicon carbide’s varied properties make it an effective material in many different applications.
Green Silicon Carbide is extremely pure & extremely hard, coming in at a Knoop 2600. It is typically only used for high tech, critical applications due to its cost. Like black silicon carbide, it will splinter as it breaks down, making excellent for recycling. It is the media of choice for wire sawing and sintering. It also has a high thermal conductivity.
UNLESS your application requires an extremely pure SiC, by default, Black SiC is preferred due to its more economic pricing, as well as availability. Right now there is a worldwide shortage of Silicon Carbides, especially Green Silicon Carbides and price are steadily rising. If you can use Black instead of Green, it is highly suggested you do so.

- Q: What does fire-resistant insulation coating have?
- Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature. Hope it is helpful to you.
- Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?
- In general, external wall thermal insulation materials can be divided into level A and level B by combustion grading. Level A is non-combustible material, and level B is combustible materials. A few years ago, the fire of the CCTV Building and Shenyang Hotel put the blame on the level B material. At present, the level A material is widely used, and the prices of same level A materials may be even cheaper than the level B material. Level A material is generally divided into thermal?mortar, phenolic foam board, rock wool board and foam cement board. I hope this information can be helpful to you. Hope you adopt.
- Q: Does the production of refractory belong to advanced technology？
- Refractories belong to the area of new materials which is one of the eight areas that are supported by the state. Whether it can be declared as high-tech enterprises or not depends on the intellectual property, personnel and finance of the company.
- 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: Who knows about the criteria of fireproof and thermal insulation materials?
- 1. thermal insulation materials with A-level combustion performance: EPS sea capacity module, rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. thermal insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), phenolic aldehyde, gelatine powder polyphenyl granule,etc. 3. thermal insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc. Such A-level insulation materials are only fireproof, the thermal insulation properties are worse than that of organic XPS \\EPS materials. Currently I think that the best insulation material should be EPS sea capacity module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The thermal insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range. I hope my answers help you.
- Q: The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide
- 1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.
- Q: What are included in fireproofing materials?
- There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.
- Q: Manganese steel belongs to refractories
- NO!
- Q: What is refractory cement?
- The introduction of properties and chemical composition of refractory cement. Refractory cement usually refers to the cement with calcium?aluminate as the mian compopnent. Refractory cement is a monolithic refractory. It is in particular a basic binder of castable refractory. Its chemical composition is mainly Al2O3 and CaO, and some contain a considerable number of Fe2O3 and SiO2.
- Q: how long is the fire endurance of plasterboard?
- Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
