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. Vickers microhardness ranges from 3000-3300 kg/mm2 to 2670-2815kg/mm2. Knoop hardness ranges between 2770-2815 kg/mm and 3300 mm per cubic meter. It’s second only to diamond and cubic boron-nitride in the abrasives market, surpassing corundum. The silicon carbide abrasive’s density is about 3.20 g/cm3. It has a natural bulk density between 1.2 to 1.6 g/mm3, while its specific gravity of 3.20 g/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 better performance, however, it comes at a high cost.

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 can withstand acidic, alkali and molten salts up to 800°C.

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 degrees C, is what makes it self-conducting. The product was then crushed into granular crystals and graded. The silicon carbide powder in its crude (>10mm) grade cannot be sintered at a high density. Use silicon nitride/silicon oxynitride 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.

Also, carbon’s solubility is high in liquid silicon. It can be extracted by crystallization of carbon-rich, supersaturated molten silica at high temperatures (1650degC).

The reaction that resulted was the base of either mature self-bonding, reaction bonding technology or fine-grained Silicon Carbide powder.

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 coefficients of thermal expansion it’s a good material choice 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 used for the first and second walls as well as cover assemblies 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 is used 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. By releasing more energy, the furnace can treat more waste for the same amount as molten iron. 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” (or simply “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.
