The next step — scaling mm wafer production to high-volume — is anticipated to occur over the next 12 to 18 months. Parallel improvements to SiC epitaxy — the deposition of SiC semiconductor layers with different doping concentration by a chemical vapor deposition process — have also been critical to .   The chemical vapor deposition (CVD) of silicon carbide (SiC) on carbon has been widely used as a general method to suppress dust generation on carbon surfaces. For a CH3SiCl3 (MTS) and hydrogen system, computational fluid dynamic simulations to predict the growth rate of the silicon carbide are performed. The results of the simulations are consistent with the experimental results .

A variety of ceramic composite components have been fabricated by a combination of chemical vapor infiltration (CVI) and chemical vapor deposition (CVD) of silicon carbide. The vapor pressure of silicon and the dissociation pressure of silicon carbide have been obtained from total weight loss experiments with Knudsen effusion cells. Combination of the measured data with known entropies yields at °K for the heat of sublimation of silicon to silicon atoms ±3 kcal and for the heat of the reaction SiC (s.

Chemical vapour infiltration (CVI) is a ceramic engineering process whereby matrix material is infiltrated into fibrous preforms by the use of reactive gases at elevated temperature to form fiber-reinforced composites.

The earliest use of CVI was the infiltration of fibrous alumina with chromium carbide. CVI can be applied to the production of carbon-carbon composites and ceramic-matrix.
