Silicon Carbide SiC Pulp:
SiC Silicon carbide It is lightweight and strong ceramic material that can be used in place of diamonds. Silicon carbide is This ceramic material is excellent for applications that require high temperature resistance, good erosion resistance, and abrasive resistance.
Silicon carbide Also known by the common name emery (a type of semiconductor), it is silicon carbide semiconductor . Silicon carbide can be very hard. It is made from synthetic carbon and silicon. Silicon carbide Formula chemical The SiC. SiC has been a key material for cutting and grinding tools since the late 19th century.
Microscopic silicon carbide powders are hexagonal crystals. Their Mohs hardness is 9.2, their Vickers microhardness lies between 3000 and 3300 kg/mm2, and Knoop's hardness at 2670 to 2815 kg/mm. They also have a microhardness of 3300 mm per cubic meter. It's second only to diamond and cubic boron-nitride in the abrasive industry, surpassing corundum. Its density is about 3.20 g/cm3. The silicon carbide abrasive's natural bulk density is between 1.2-2.6 g/mm3. And the specific gravity of 3.20-3.25. 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 This non-oxide ceramic is suitable for use in many products, which must perform in high thermal (high temperature and thermal shock), and other demanding environments. SiC, which is single crystal, has the highest performance, however, it comes at a high cost.
Silicon carbide is made up of an equihedron of silicon atoms, and strong bonds in its crystal lattice. It is very durable. Silicon carbide can withstand acidic, alkali and molten salts up to 800C.

It is simple. Silicon Carbide SiC Powder produced ?
Making silicon carbide is easy. Simply mix silica and carbon in an Acheson Graphite Resistance furnace at temperatures high between 1600degC (2.910degF), and 2,500degC (4.530degF).
Silica carbide (commonly known as silicon carbide) is made by reacting coke (carbon), and sand (silica) in resistance furnaces.
Heating the mixture with direct current, to temperatures as high as 2700 degC, is possible. A few days later, the product was made from iridescent crystal aggregates. These were then graded and crushed. The silicon carbide powder in its crude (>10mm) grade cannot be sintered at a high density. Use silicon oxynitride (or silicon nitride) for refractory uses. When direct bonding of the desired degree can be achieved, high-purity, gradient silicon carbide is sintered at temperatures of around 2400°C. High density materials (low porosity), require special conditions.
You can make silicon carbide by decomposing gaseous and volatile carbon compounds in an inert atmosphere. 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 molten silica at high temperatures (1650°C).
This was what formed the base of mature self bonding, reaction bonding technology and fine-grained silicon caride powder.

Make use of 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 cover wall and initial walls of the nuclear fusion reactor. You can use candidate materials to cover nuclear fuel particles that are high-temperature, gas-cooled reactors. Additionally, silicon carbide is used for many other purposes.

SiC cutting disk for grinding and cutting
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.
Material for construction
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.
Auto 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 some high-performance vehicles, such as Porsche Carrera GT, Bugatti V8 and Chevrolet Corvette ZR1, McLaren P1, Bentley and Lamborghini, and certain high-performance Audi models. Also, silicone carbide can be found in 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 small or large casting applications.
Electronic circuit 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.
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. With the extra energy, the furnace can treat more waste and produce more molten steel. This energy can be used to adjust the carbon or silicon content, and raise the tapping temperature.
The gemstone silicon carbide used as jewelry is "Synthetic Moissanite", also known simply as "Moissanite", after its mineral name.
Guide to fishing rods
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 stainless or titanium. A lifting ring is a non-friction, low-friction, and hardening surface. This can help improve casting distance while preventing the fishing line braids from getting damaged.
