Silicon Carbide (SiC)
General description: The molecular formula of silicon carbide is SIC, it is generated
by SiO2 and petro coke or anthracite through reduction reaction
under the condition of high temperature, there are two kinds of it:
black SIC and green SIC. Green SIC is produced by putting NaCl into
the raw material during the processing period whose properties are
better than the black SIC of the same grade.
Properties:Physical properties of SIC is extreme hardness, high
temperature-resisting ,chemical erosion resisting, radiation
resisting and good electric conductivity and thermal conductivity,
low thermal expansion, it`s Moh`s hardness is 9-9.5.
Usage: It is widely used in the fields of abrasive, grinding, heat
resistance, electronics, aviation, metallurgy and ceramics and so
- Used as abrasive materials
- Used as deoxidizer and high-temperature resistant material
- High purity material can be used in producing semi-conductor.Sic
Silicon Carbide Lumps
Size: 0-10MM/1-10MM/1-5MM/0-25MM/0-100MM or as per buyer`s
packing:1mt plastic woven bags or as per buyers` requirement.
Processing method:Crushing and so on.
Due to its stable chemical properties, high thermal conductivity,
small coefficient of thermal expansion and good wear resistance,
silicon carbide has many other applications besides abrasive
materials. For example, silicon carbide powder can be coated on the
turbine wheel or the cylinder block in a special process The inner wall can improve its wear resistance and extend the
service life of 1 to 2 times; to be made of advanced refractories,
heat shock, small size, light weight and high strength,
Low-grade silicon carbide (about 85% SiC) is an excellent
deoxidizer that accelerates the rate of steelmaking and facilitates
the control of chemical composition and the quality of the steel. In addition, silicon carbide is also used extensively in the
production of silicon carbide rods for electric heating elements.
Pure silicon carbide is a colorless and transparent crystal. Industrial silicon carbide due to the impurities contained in
different types and content, but pale yellow, green, blue and even
black, with its purity varies with purity.  Silicon carbide crystal structure is divided i
