Silicon carbide — Wikipedia Republished // WIKI 2
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).

Since its shape offers a higher symmetry, electrons ster less making it the Silicon Carbide structure with the highest maximum electron low-field mobility at room temperature (1000 cm 2 /Vs 1). On the other hand, 6H-SiC (six bilayers in a hexagonal lattice) may have less interesting electrical properties with an electron mobility of 380 cm 2 /Vs, but its lesser symmetry makes it much easier

Silicon Lattice - TU Wien
The crystal lattice of silicon can be represented as two penetrating face centered cubic lattices (fcc) with the cube side a =0.543nm as portrayed in Figure 3.1. The structure is visualized as a tetrahedron with four vertices of the first fcc lattice at (0,0,0), ( a /2,0,0), (0, a /2,0) and (0,0, a /2) and an additional atom added to the center of this tetrahedron.
