Silicon carbide has two commonly used basic varieties, black silicon carbide and green silicon carbide, both of which belong to α-SiC. 1.Black silicon carbide contains about 95% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. 2.Green silicon carbide contains more than 97% SiC and has good self-sharpening properties. In addition, there is cubic silicon carbide, which is a yellow-green crystal made by a special process. The abrasive tool used to make it is suitable for super-finishing of bearings, and the surface roughness can be processed from Ra32~0.16 microns to Ra0.04~ 0.02 microns.
Black Silicon Carbide is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand ,petroleum coke
The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.
Black silicon carbide's mechancial intensity is greater than fused alumina, but brittle and sharp.
Black silicon carbide has some electrical and heat conductivity.

Silicon carbide has four main application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. Coarse silicon carbide materials can already be supplied in large quantities and cannot be regarded as a high-tech product. The application of nano-scale silicon carbide powder with extremely high technical content is unlikely to form economies of scale in a short time.
1.As an abrasive, it can be used to make abrasive tools, such as grinding wheels, oilstones, grinding heads, sand tiles, etc.
2.As a metallurgical deoxidizer and high temperature resistant material.
3. High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.
Main application: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.
Used in semiconductors, lightning rods, circuit components, high temperature applications, ultraviolet light detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic films, cutting tools, heating elements, nuclear fuels , Jewelry, steel, protective gear, catalyst carrier and other fields.
Q1. Can I see the sample first before I place the real order ?
A1. Of course. We can offer little sample for testing quality and market.
Q2. What products can you supply ?
A2. We are specialized in refractory such as magnesite,SIC,bauxite and GPC.
Q3. Are you a manufacturer or trading company?
A3. We are a manufacturer with more than 20 years experience.
Q4. What is the delivery time?
A4. It is not fixed and depend on your order quantity.Usually, it will take 7~15 days.
