Silicon carbide | chemical compound | Britannica

Silicon carbide: Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found appliion

Silicon

The silicon produced via this process is called metallurgical grade silicon and is at least 98% pure. Using this method, silicon carbide, SiC, can form. However, provided the amount of SiO 2 is kept high, silicon carbide may be eliminated, as explained by this equation: 2 SiC + SiO 2 → 3 Si + 2 CO.

Silicium | Article about Silicium by The Free Dictionary

Pure semiconductor silicon is produced in two forms: poly-crystalline (by the reduction of SiCI 4 or SiHCI 3 with zinc or hydrogen or by the thermal decomposition of SiI 4 and SiH 4) and single crystals (by floating zone refining and by “withdrawing” a single crystal from molten silicon—the Czohralski method).

Growth of silicon carbide bulk crystals by physical …

Silicon carbide bulk crystals were grown using the physical vapor transport (PVT) method. Crystal growth modeling was used to obtain the required inert-gas pressure and temperatures for sufficiently large growth rates. We expanded the crystals by designing a growth chaer which has a positive temperature gradient along the growth interface.

Analysis of polytype stability in PVT grown silicon

2019-3-19 · Polytype stability is very important for high quality SiC single crystal growth. However, the growth conditions for the 4H, 6H and 15R polytypes are similar, and the mechanism of polytype stability is not clear. The kinetics aspects, such as surface-step nucleation, are important. The kinetic Monte Carlo method is a common tool to study surface kinetics in crystal growth.
