Product Description:


Specifications of SiC:


Black SIC And Green SIC lump,grain,grit and micropowder for refractory or abrasive. Size can be based on customer's requirement.


- Description:
    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.


- 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.
- Partical Size:
   ♦Lumps: 0-20mm, 0-50mm.
   ♦Grains: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 0-10mm, 1-10mm, etc. 7/14, 14/30, 36/70, etc.

                   -100mesh, -200mesh, -325mesh, etc.

Q:How to extinguish the charcoal fire?
Charcoal air on the line, but also can use water, but there will be a lot of gases
Q:What materials can be carbonitriding?
Low temperature carbonitriding for high alloy tool steel, high-speed steel tools, etc., in temperature carbonitriding is under great pressure not only in carbon steel wear parts, high temperature carbonitriding is mainly used for medium carbon steel and alloy steel under great pressure.
Q:What is the basic principle of carbon fourteen detection?
Carbon fourteenCarbon fourteen, a radioactive isotope of carbon, was first discovered in 1940. It is produced by hitting twelve carbon atoms in the air through cosmic rays. Its half-life is about 5730 years, the decay is beta decay, and the carbon 14 atoms are converted to nitrogen atoms. Since its half-life is 5730 years, and carbon is one of the elements of organic matter, we can infer its age by the 14 component of the residual carbon in the dying organism. When living in the biological, because need to breathe, the carbon content of 14 in its body is about the same, the organisms die will stop breathing, at this time the carbon 14 in the body began to decrease. Since the proportion of carbon isotopes in nature is always stable, one can estimate the approximate age of an object by measuring its carbon 14 content. This method is called carbon dating. Other commonly used methods include potassium argon measurements, potassium argon measurements, thermoluminescence measurements, and others;
Q:Organic matter is converted from organic carbon. Why is humus represented by carbon instead of converted?
Soil organic matter refers to all organic matter in the soil, due to the size of the organic matter content of different soil in a composition is more complex, but are not necessarily organic carbon containing material, so there is a mathematical relationship between soil organic matter and organic carbon. In general, we are the first to measure the content of soil organic carbon, and then use the formula to convert the content of organic matter.
Q:What are the carbon monoxide collection methods?
It can only be collected by drainage. Carbon monoxide is not soluble in water. Because carbon monoxide is poisonous and the density is very close to the air, it can not be collected by exhaust air
Q:Why vegetarianism can reduce carbon emissions?
This specific or calculated, and if you have done ISO14064, you should know that every year will be the carbon emissions statistics, the general is your year of all activities in accordance with the corresponding CO2 coefficients into CO2 equivalent;If you eat according to statistics, that is to calculate what you eat, how much CO2 is needed to produce;
Q:The outer and inner carbon carbon ribbonA recent study of ribbon,
In fact, to teach you a simple way to distinguish between internal and external carbon, carbon, label paper dip ribbon, with black on the outside of the outer side is carbon, carbon is in inside, no performance difference, now generally used is the most carbon, such as the machine is to use carbon is better, because the wound is not the same, sometimes loose.
Q:What is the burning point of carbon?
There are many forms of carbon, such as charcoal, coal, and even diamonds!And different forms have different ignition points!Generally speaking, the ignition point of charcoal is relatively low, about 300 degrees, and the coal is higher, at 600 - 700 degrees!
Q:The main difference between steel and iron is the difference in carbon content
Steel carbon content is 0.03% ~ 2% of the iron carbon alloy. Carbon steel is the most commonly used ordinary steel smelting, convenient, easy processing, low price, and can satisfy the use requirement in most cases, it is widely used. According to the different carbon content, carbon steel is divided into low carbon steel, medium carbon steel and high carbon steel with the carbon content increased, decreased the hardness, toughness of carbon steel alloy steel. Also called special steel, adding one or more alloying elements in steel on the basis of the change of microstructure and properties of steel, it has some special properties, such as high hardness, high wear resistance, high toughness and corrosion resistance sex, etc.
Q:What's the use of carbon 60?
Used to strengthen metals; used as a new catalyst for storage of gases
