High Purity Silicon Carbide SiC CAS 409-21-2,99%

Silicon carbide, also known as SiC (silver carbide) ceramic material has high-strength properties that are comparable to those of diamond. Silicon carbide powder has hexagonal crystals at its microscopic size. Purity: 99% Silicon Carbide SiC Pulp: SiC Silica carbide , a light ceramic material that has similar strength to diamonds, is . Silicon carbide can be used in applications that require high temperature resistance, good erosion resistance, and resistance to abrasion. Silicon Carbid also called “emery”, which refers to a typeof semiconductor, namely Silicon Carbid. Silicon carbide Chemical formula Is SiC. It is hard. The use of silicon carbide in cutting tools, sandpaper and grinding wheels has been a major part of modern society since the late 19th century. Microscopic silicon carbide powders are hexagonal crystals. Their Mohs hardness is 9.2, their Vickers microhardness 3000-3300kg/mm2, and Knoop microhardness 2670-2815kg/mm2. The microhardness (3300 mm/cubic millimeter) is 3300mm. It has a higher density than corundum and is second only to diamond and cubic boron-nitride. Its density is about 3.20 g/cm3. The silicon carbide abrasive’s natural bulk density is between 1.2-2.6 g/mm3, while its specific gravity of 3.20-3.25 is. As its primary raw material, green silicon carbide is made from petroleum coke and high quality silica. Salt is used as an additif. At high temperatures in resistance furnaces, its hardness equals that of diamond. Additionally, it has higher mechanical strength and harder than corundum. Silicon carbide ceramic is non-oxide and can be used to make many items that are subject to high temperature (high thermal, and/or thermal shock) or mechanically challenging applications. SiC single crystal has the highest performance, but it is expensive to manufacture. Silicon carbide is made up of an atom-tetrahedron composed of silicon and carbon. There are strong bonds in its crystal lattice. It is very durable. Silicon carbide will not be corroded by acids, alkalis or molten sodium above 800°C.

Simply mix silica and carbon in an Acheson Graphite Resistance furnace at temperatures high between 1600°C (2.910°F), and 2,500°C (4.530°F). Silica carbide (commonly known as silicon carbide) is made by reacting coke (carbon), and sand (silica) in resistance furnaces. After heating the mixture with direct current, temperatures as high as 2700°C are reached, it is then produced from iridescent crystal aggregates. These were crushed and graded. Silicon carbide powder in the crude (>10m), grade cannot be sintered at a high density. Use silicon nitride/silicon oxynitride, an aluminosilicate or binder phase (self-bonding silicon and carbon) to bond the compacted silicon carbide sand in refractory uses. If the desired degree of direct bonding of the electric heating element material can be achieved, then the high-purity, gradient silicon carbide is sintered at approximately 2400°C. You can make silicon carbide by melting the volatile and gaseous silicon compounds in an atmosphere that is inert. This allows you to deposit the reactant on a suitable thermal substrate. Finally, carbon’s solubility is high in liquid silicon. It can be extracted by crystallizing carbon-rich, supersaturated SiC at high temperatures (1650°C). The reaction that resulted was the base of either mature self-bonding, reaction bonding technology or fine-grained Silicon Carbide powder.

Use Silicon Carbide SiC powder: People are very interested in silicon carbide as a functional material used in many optical and semiconductor devices. Because of its excellent stiffness and high conductivity as well as low coefficient of thermal extension, silicon carbide is an ideal material for large-scale optical mirror applications. Additionally, silicon carbide is used as a barrier for electronic equipment at high temperatures and parts that are susceptible to mechanical wear such as bearing parts or seals. SiC is also used for the first and second walls, as well as cover assemblies of the nuclear fusion reactor. Candidat materials can be used to cover nuclear fuel particles of high-temperature, gas-cooled reactors. Grinder and Cutting Tools SiC Cutting disc Because of its durability and low price, silicon carbide is very popular in the manufacture of modern gems. Because of its hardness, silicon carbide material is often used in grinding, honing or water jet cutting. Structural material Silicon carbide is used in high temperature furnaces as support material and shelves. It can also be used for casting glass, glass fusion, or firing ceramics. SiC kiln racks last longer than traditional Alumina racks. Car parts Porsche Carrera GT’s disc brakes are made from carbon ceramic (silicon-caride) High-performance brake discs made of siliconized carbon-carbon alloys are possible because they can withstand high temperatures. This brake disc is used in various road cars, super cars, and high-performance vehicles such as Porsche Carrera GT. Also, silicone carbide is used to create diesel particulate filter in sintered forms. Silicon carbide is used to decrease friction, emissions, and harmonics in oils. Casting silicon carbide crucible SiC is used for holding the molten iron in both small and large casting operations. Electronic components Silicon carbide is the commercially most important semiconductor material. Henry Harrison Chase Dunwoody, also known as Henry Harrison Chase Dunwoody, applied for a patent in 1906 for a crystal radio detector diode called “silicon caride”. This technology was widely applied in shipboard receivers. A stronomy High hardness and rigidity as well as a low coefficient of thermal extension make silicon carbide a good mirror material for astronomical telescopes. Filament pyrometer The glowing SiC fibre and test flame. About 7 cm (2.28 inches) in height, the flame can be seen. To measure gas temperature in optical technology (called the filament high–temperature method), silicon carbide fibers can be used. Graphene production You can use silicon carbide to make graphene. Its chemical properties allow for the epitaxial production graphene at SiC nanostructures. Steel production Wafers of silicon carbide for steelmaking. In an alkaline oxygen furnace, silicon carbide can be dissolved and then used as a fuel. The furnace can produce more energy with less molten iron because it has less waste. This energy can be used to adjust the carbon or silicon content, and raise the tapping temperature. Jewelry The gemstone silicon carbide used as jewelry is “Synthetic Moissanite”, also known simply “Moissanite”. Fishing rod and reel guide Fishing tackle is made from silicon carbide because it has wear resistance and durability. In order to keep the pipe from touching the bar stock the silicone carbide ring must be installed within a guide frame. This is often made of titanium or stainless steel. A lifting ring is a non-skid surface with low friction that improves casting distance while also providing enough hardness to protect the fishing line.
