Silicon uses widely as a semiconductor material due to its high abundance, moderate band gap, easy fabriion, crystal structure and silicon dioxide. Quartz is made to react with coke to produce metallurgical silicon in an electric furnace. The metallurgical silicon is then converted to trichlorosilane (TCS) in fluidized bed reactors.

Silicon carbide (SiC) electric heating elements for element temperatures up to 1625 C (2927 F), available in a wide variety of standard sizes and geometries, or in customized designs to meet the specific needs of various processes and equipment. Grade Description
We have studied intrinsic and impurity related defects in silicon carbide (SiC) epilayers grown with fast epitaxy using chemical vapor deposition in a vertical hot-wall reactor. Using capacitance transient techniques, we have detected low concentrations of electron traps (denoted as Z 1/2, EH6/7 and titanium) and hole traps (denoted as HS1 and shallow boron) in the n-type 4H–SiC epilayers.
The surface roughness of n-type polycrystalline 3C silicon carbide was decreased from 17.3 nm to 8.3 nm (rms roughness) after EP at current density 10 mA/cm 2 in HF 1 wt.% for 30 min .
