Silicon carbide | chemical compound | Britannica

Discovery. Silicon carbide was discovered by the American inventor Edward G. Acheson in 1891. While attempting to produce artificial diamonds, Acheson heated a mixture of clay and powdered coke in an iron bowl, with the bowl and an ordinary carbon arc-light serving as the electrodes. He found bright green crystals attached to the carbon electrode and thought that he had prepared some new ...

Silicon Carbide (artificial): Mineral information, data ...

Artificial silicon carbide (SiC) is included in this database as samples of it are frequently sold in "rock shops" and on internet auctions, sometimes under the name 'carborundum', sometimes as 'moissanite' (there is a very rare natural silicon carbide mineral with the name moissanite), but most frequently with no name at all. It is easily recognised by its dark blue-black colour, rainbow ...

Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications ...

Siliciumcarbide - Wikipedia

Productie. Granulair siliciumcarbide wordt op commerciële schaal geproduceerd door een reactie bij zeer hoge temperatuur. Hoogwaardig silicazand en koolstof (meestal petroleumcokes) worden hiervoor in de juiste verhouding tot reactiemateriaal gemengd.Van dit mengsel wordt een hoop opgebouwd (de "oven").

Silicon Carbide SiC - STMicroelectronics

Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher, heat dissipation is improved and switching and conduction losses are lower. However, wide bandgap materials are more difficult to mass produce compared to silicon based ones.

Moissanite - Wikipedia

Moissanite (/ ˈ m ɔɪ s ən aɪ t /) is naturally occurring silicon carbide and its various crystalline polymorphs.It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide is useful for commercial and industrial applications due to its hardness, optical properties and thermal conductivity.
