Product Description:

High Purity SiC for Refractory Black Color



Black Silicon Carbide 
1.long years' professional experience. 
2.Controlled composition&size. 
3.High energy



Silicon carbide (SiC) is made from quartz sand and petroleum coke( or coal tar), wood chips as raw material through high temperature smelting in electric resistance furnace.



1.metallurgical deoxidizer

2.high temperature resistant materials abrasive, abrasive tools can be used to such as grinding wheels, whetstones, grinding head, sand tile etc



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:How much is refractory spraying coatings?
Different brands and models have different prices. For example: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Hengli | Product category: dedicated castable for biomass burning machine | Material: castable Price: 3000.00 refractory temperature: 1770 ~ 2000 ℃ | Brand: Great Wall | Category: unshaped refractory material | Material: corundum mullite Price: Refractory temperature: 1580 ~ 1770 ℃ | Brand: Guanghuayaoye | Product category: refractory material| Material: high alumina Price: 2500.00 The above prices obtained from the Internet are for reference only, and please pay attention to the purchasing price.
Q:What antioxidant will be used in refractories?
Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:What are fire resistant level standards of class A fire resistant door?
Situations under which fire endurance should at least meet class A fire resistant door standard: In basement, the fire door for room where the stored combustibles average weight exceeds 30kg/㎡; in partition basement, the fire door for partition of room where the stored combustibles average weight exceeds 30kg/㎡; in high building, the fire door for equipment room of automatic fire extinguishing system, fan room and air-conditioner room; in boiler room, transformer cabin, diesel generator room(other dangerous rooms), the fire door in firewall. These places are special and need high security, so they need to meet the standard of class A fire resistant door. What is class A fire resistant door? New Standard for Fire Door GB12955-2008 provides that class A fire resistant door thermal insulation and refractory integrity should be no less than 1.5 hours. In other words, the key of fire door grade is the fire-resistant time. Class A fire resistant door size: class A fire resistant doors have many sizes, and can be customized according to the needs of customers. For example, the size of some fire doors of the diesel generator room is large, while the size of fire doors of basement storing combustibles is small. So the size of class A fire resistant door is also different. Usually Xinduo will take this into account, produce class A fire resistant door with various sizes and can customize according to customer requirements. Class A fire resistant door standard: as is mentioned above, for class A fire resistant door standard, the key is the fire resistant time, no less than 1.5 hours. In texture, class A fire resistant door standard is manifested in the firm joint, uniform distribution of solder joints and smooth surface coating. It has also set fireproof sealing strip which should be straight.
Q:Fefractory of aluminium oxide.
Do you mean the alumina hollow ball brick? We can exchange private messages in specific.
Q:What is the function of red stone refractory materials
Q:For refractory, what is critical particle size? Thank you.
Q:What is shapeless refractory with high performance?
The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
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:Which fire-resistant materials have good viscidity?
Viscidity is necessary for gunning mix, repair mix and bordering. It is too broad to which has good viscidity. Both gunning mix and repair mix are powder before adding water. Bordering also has little viscidity before heating. The question shoule be more specific.
