Product Description Silicon Carbide PowderSiC is harder and more durable than diamond, with improved thermal resistance. Furthermore, it resists corrosion better than most ceramic materials.Pure silicon carbide (SiC) is colorless while industrial SiC typically exhibits brown to black hues due to iron impurities. When doped with nitrogen, phosphorus or aluminium it becomes a semiconductor and becomes semiconductor device.Purity of SiC is of utmost importance as its performance and applications rely on it. To maintain high purity levels, rigorous raw material screening and purification processes must take place.Particle Size DistributionSilicon Carbide powder is an advanced material with numerous physical and chemical properties that make it stand out. As one of the hardest materials found in nature - second only to diamond - SiC shows excellent wear resistance as well as low thermal expansion and high thermal conductivity properties.Since 1893, SiC has been mass produced for use as an abrasive. Granules of SiC can be joined together via sintering to produce hard ceramics, such as those found in bulletproof vests. SiC crystals may also be cut for decorative purposes or grown using Lely method to produce large single crystal mirrors for use with telescopes.Green SiC powder features narrow particle size distribution and small voids, making it a highly sought-after raw material for functional ceramics, advanced refractories and abrasives. Available either bulk or vacuum sealed bags/drums for safe storage/handling/exposure management purposes, proper storage and handling must be prioritized to prevent respiratory irritation and long-term exposure risks.PuritySilicon carbide powder purity plays a pivotal role in its performance and application. High purity SiC contains minimal levels of impurities, making it suitable for applications such as semiconductor material processing where any impurities could negatively affect final products.Green silicon carbide micropowder is widely used to produce abrasives and cutting tools due to its hardness, thermal stability and chemical resistance. Furthermore, it serves as a key raw material in producing single-crystal and polycrystalline wafers used in semiconductor production.Silicon carbide can be doped with nitrogen or phosphorus to create n-type or p-type semiconductors for LED production and other optoelectronic applications.silicon carbide is widely recognized for its low thermal expansion rate, making it an ideal material for mirrors used in astronomical telescopes. Furthermore, SiC can be found in refractories and ceramics for its heat resistance and mechanical strength as well as being utilized in car brakes, clutches and bulletproof vest ceramic plates. Its durable properties also make SiC an important component.Physical PropertiesAt least 70 crystalline forms of silicon carbide exist, with Alpha Silicon Carbide (a-SiC), with its hexagonal crystal structure similar to that of wurtzite being the most often encountered form. Black Silicon Carbide (b-SiC), on the other hand, is often utilized in applications requiring high endurance such as automobile brakes and car clutches; additionally it is often found used as support material for heterogeneous catalysts due to having higher surface areas than alpha SiC forms.sic powder boasts the second-highest Mohs hardness rating after diamond. Due to its excellent thermal conductivity, semiconductor behavior, and resistance to oxidation at high temperatures, silicon carbide is an ideal material choice for components like heat exchangers that must perform under extreme environmental conditions.Ceramic materials that can withstand acid corrosion typically come in the form of water-soluble ceramic materials that are water and alcohol soluble, such as SiO2, making storage in airtight containers or protective packaging necessary to prevent moisture contaminating its powder form.ApplicationsSilicon carbide powder has numerous industrial applications. It can be used in abrasive machining processes like grinding and water-jet cutting, as well as wet/dry sanding operations used to fine grind materials such as ceramics, ferrous metals, glass and stone; in some cases even soft metals like aluminum alloys and zinc!SiC is also widely employed as the raw material for creating cubic silicon carbide (c-SiC) wafers via either Lely process or chemical vapor deposition; C-SiC wafers feature high decomposition temperatures and superior oxidation resistance properties.Green silicon carbide micropowder is widely used as a refractory material in manufacturing ceramic, glass and metal products due to its durability and high thermal shock resistance. Additionally, its durability makes it useful in aerospace and automotive industries for honing and polishing metal and ceramic components for precise dimensions and smooth finishes; additionally it's essential in developing materials for kiln furnace walls and muffles.
