Doping in cubic silicon–carbide: Applied Physics Letters

We studied the energetics and the properties of impurity states that result from doping cubic silicon–carbide (3C–SiC) with aluminum (Al), boron (B), and nitrogen (N) atoms using the tight-binding linear coination of muffin-tin orbital atomic sphere approximation method. For Al doping, it is only favorable to substitute Al for Si atoms. The corresponding hole states contribute to a

Moissanite: Mineral information, data and localities.

Moissanite, found as tiny crystals in some meteorites (originally formed in star dust) and kierlites, is a naturally occurring silicon carbide, SiC (in synthetic form a very important high-performance ceramic, more commonly known as abrasive "carborundum").A large nuer of polytypes (predominantly hexagonal or rhoohedral) is known.

mp-7631: SiC (hexagonal, P6_3mc, 186) - Materials Project

SiC is Moissanite-6H structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four C4- atoms to form corner-sharing SiC4 tetrahedra. There is three shorter (1.89 Å) and one longer (1.90 Å) Si–C bond length.

Moissanite - Main Page - Wikipedia, the free encyclopedia

Background. Moissanite was discovered by Henri Moissan while examining rock samples from a meteor crater loed in Canyon Diablo, Arizona in 1893.At first, he mistakenly identified the crystals as diamonds, but in 1904 he identified the crystals as a new mineral and called it silicon carbide (SiC).

What’s the difference between Swarovski Crystal, Diamonds

Mar 25, 2012· What’s the difference between Swarovski Crystal, Diamonds and Cubic Zirconia? It’s made from Silicon Carbide which means it’s able to withstand high temperatures and is very hard with a Mohs scale reading of 9.25. There is currently only one manufacturer of Moissanite gemstones, Charles & Colvard who have a patent that will expire in

Cutting tool materials

Cemented carbide is a powdery metallurgical material: a composite of tungsten carbide (WC) particles and a binder rich in metallic cobalt (Co). Cemented carbides for metal cutting appliions consist of more than 80% of hard-phase WC. Other important components are additional cubic carbonitrides, especially in gradient-sintered grades.
