Product Description:

Specifications of Black Silicon Carbide:


Black silicon carbide grit F 24-240, sic 98.5%min, F.C 0.2%max, Fe2O3 0.3%max. Packing:25kg bags be packed into 1mt big bags. 



- Description:

Black 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.

- Specification:

Grits: F12-90, F100-240.

Q:How dnf advanced carbon ashes?
Before 70, strengthening with carbon, then the activities in the mall to sell high carbon, have to use coupons to buy, that is to improve the success rate of strengthening, now is also the time to rest, 80 edition, replaced by strengthening the body of the colorless, carbon was automatically replaced colorless (1: 5) senior carbon system did not automatically change on the left
Q:What are the basic structures of iron carbon alloys?
The symbol is A. The stable austenite has a temperature of 727 DEG C, when the solubility of carbon is 0.77%, the strength, hardness and plasticity of austenite are very good, which is the organization required for high temperature forging or rolling of most steels.Cementite: a metallic compound of iron and carbon with a carbon content of 6.69%. The formula Fe3C is expressed in symbolic Cm. High hardness, poor plasticity, hard and brittle, the number of cementite increases, strength and hardness increase, while plasticity decreases.
Q:What are the carbon monoxide collection methods?
Drainage methodExhaust air cannot be used because CO is poisonous
Q:Why is carbon content of stainless steel low?
The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel is lower, the maximum is not more than 1.2%, and some steel's Omega C (carbon content) is even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), and the steel has corrosion resistance only when the Cr content reaches a certain value. Therefore, stainless steel in general Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
Q:Carbon emissions trading stocks latest list of carbon emissions trading stocks what?
Carbon trading concept of a total of 21 listed companies, of which 12 carbon trading concept listed companies trading on the Shanghai Stock Exchange, and 9 other carbon trading concept listed companies trading in the Shenzhen stock exchange.Automatic matching based on the cloud financial leading excavator, carbon trading stocks leading shares most likely from the following stock was born in Tianke, electrical, environmental protection up to confidence.
Q:Glucose contains resveratrol (C14H12O3) to determine the mass ratio of resveratrol and carbon dioxide of the same quality as carbon dioxide
They are x and y, containing carbon equal, according to the mass of an element = the mass of a compound * the elementMass fractionFor C14H12O3, the carbon mass fraction is C%=12*14/ (12*14+12+16*3) *100%=73.68%For CO2, the mass fraction of carbon is 12/ (12+16*2) =27.27%There is x *73.68%=y*27.27%So there's X: y =57:154
Q:Organic matter is converted from organic carbon. Why is humus represented by carbon instead of converted?
Therefore, only there is a certain relationship between soil carbon content and soil organic matter, high carbon content of soil humus certain, but it does not explain the soil organic matter, because organic matter contains not only the humus, also contains many other organic substances are not decomposed.
Q:How to distinguish between good and bad carbon carving?
General consumers believe that bamboo charcoal, powder, charcoal and purple carbon carving are "carbon" to do, and the former is very cheap, why not buy them, in fact, otherwise, because not the same kind of products. Bamboo charcoal and powdered activated carbon have little effect on the purification of indoor air. Their function is not different from that of a pack of quicklime - adsorption of water vapor. But consumers are not aware of this, they also propaganda have the function of purifying air and we mixed together to sell, finally, once consumers buy found not what role, will also lose confidence in carving, which makes us very sad.Let's talk about bamboo charcoal first. Charcoal is not a purple carbon carving, this is a common sense. If bamboo charcoal can also absorb toxic and harmful gases, then the main material of gas masks do not need to use more expensive activated carbon, but not sublimation of purple carbon carving, and the price of bamboo charcoal is not economical? Because the bamboo charcoal and charcoal are natural burning carbon, not activated by directional adsorption, namely, pickling, washing, activation process, the adsorption of activated carbon 1/10 is insufficient, they can have is to adjust the indoor temperature, not only this, as they advertised "bamboo charcoal is activated carbon is purple carbon carving".Say, powdered activated carbon.
Q:What are the benefits of carbon fiber?
Carbon fiber "an hand in a velvet glove lighter than aluminum," the quality, but the strength is higher than that of steel, and has the characteristics of corrosion resistance, high modulus, in the national defense and civilian areas are important materials. It has not only the intrinsic characteristics of carbon materials, but also the softness and processability of textile fibers. It is a new generation of reinforced fiber.
Q:How much carbon does it take for 4 people to barbecue?!
Hello The amount of charcoal is according to the number, the number of barbecue barbecue food and other circumstances, the amount of each person is different, generally 6 pounds of charcoal enough for 3-5 to use, recommended to get for a little extra, so is not enough, the charcoal is not expired, can not run out of the next and then, put in the house you can also clean the indoor air.
