Formation of thermal decomposition cavities in physical vapor transport of silicon carbide
349 Formation of Thermal Decomposition Cavities in Physical Vapor Transport of Silicon Carbide seen in Fig. 2) are placed in the PVT system. The system is evacuated to a pressure below 3 × 10–7 torr, then heated in stages to about 1200 C and held for 10 min or
Silicon Carbide (SiC) Mirrors - Zygo Corporation
Silicon carbide (SiC) has long been recognized as an attractive mirror material due to its superior mechanical and thermal properties when compared to conventional optical materials. However, the material properties of silicon carbide , which make the material attractive from a design standpoint, have often precluded its use when low cost and rapid delivery of an optical mirror were required.

Late formation of silicon carbide in type II supernovae | …
Abstract We have found that individual presolar silicon carbide (SiC) dust grains from supernovae show a positive correlation between 49 Ti and 28 Si excesses, which is attributed to the radioactive decay of the short-lived (t ½ = 330 days) 49 V to 49 Ti in the inner highly 28 Si-rich Si/S zone.Si-rich Si/S zone.
