Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite.Silicon carbide powder has been mass-produced since 1893 for use as an abrasive..
The growth of hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited by Hot- Wire Chemical Vapour Deposition (HWCVD) for solar cell appliions has been studied. The films were characterized for structural properties using Fourier Transform Infrared Spectroscopy FTIR, Elastic Recoil Detection Analysis (ERDA), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

The carbothermal reduction was the earliest used method for silicon nitride production and is now considered as the most-cost-effective industrial route to high-purity silicon nitride powder.  Electronic-grade silicon nitride films are formed using chemical vapor deposition (CVD), or one of its variants, such as plasma-enhanced chemical vapor deposition (PECVD):  
silicon carbide (SiC), etc. Indeed, as a practical matter, a semiconductor material other than silicon will be used only if it has some unique property that silicon does not have. For example, because of higher carrier mobilities GaAs and more recently
We provide custom thin film (silicon carbide) SiC epitaxy on 6H or 4H substrates for the development of silicon carbide devices. SiC epi wafer is mainly used for Schottky diodes, metal-oxide semiconductor field-effect transistors, junction field effect transistors, bipolar junction transistors, thyristors, GTO, and insulated gate bipolar.
Silicon carbide is interesting for high power, high temperature and high frequency appliions but its development is limited by the low quality and high cost of single-crystalline wafers. The transfer by wafer-bonding of single-crystalline SiC thin films to a polycrystalline SiC support is an attractive way for lowering the cost.
Boron Carbide Grinding Powders In terms of hardness, Boron carbide (B 4 C) with a Mohs hardness of 9.5 is third only to diamond and so makes an excellent lower cost alternative to diamond for the precision grinding, lapping and polishing of most hard materials.
Silicon carbide thin films were deposited onto silicon substrates by pulsed laser deposition technique (PLD) using purified SiC powder as target. Significant improvement of the minority carrier lifetime was obtained encouraging the use of SiC as a passivation layer for silicon.",
For high temperature or corrosive media environments, silicon carbide can be a material of choice and has the potential to open up new appliions and markets.We recently spoke with Professor Roya Maboudian of UC Berkeley about the history of silicon carbide, comparisons to silicon and other materials as well as current research and commercialization challenges and opportunities.
