Silicon carbide (SiC) is a promising material due to its unique property to adopt different crystalline polytypes which monitor the band gap and the electronic and optical properties. Despite being an indirect band gap semiconductor, SiC is used in several high-performance electronic and optical devices. SiC has been long recognized as one of the best biocompatible materials, especially in
Silicon Carbide Composites Deposited in Silicon Carbide Whiskers by CVI Process Authors: Fan Tao Meng, Shan Yi Du, Yu Min Zhang Abstract: Chemical vapor deposition (CVD) is an effective method of preparing silicon carbide whiskers or films and chemical vapor infiltration (CVI) can be successfully used as the preparation of SiC composites.
29/3/2012· 5. The method of claim 1, wherein the ceramic matrix consists of a silicon carbide composition and the thermal treatment produces a thin carbon layer on the silicon-carbide surfaces with less than 10 percent loss in fiber and composite tensile 6.
This Nature article reports on electrochemcially producing silicon carbide in molten salt at 900 C. That''s still pretty hot for the typical biological life form. Still, if the life form had an internal crucible made of silicon carbide, it is vaguely conceivable it could support a solution at 900°C.

2/5/2016· The silicon carbide monofilaments produced at TISICS have a very narrow strength distribution as a result of a carefully controlled chemical vapour deposition (CVD) process. While the monofilaments are still brittle it is possible to design composites to take advantage of their strength while protecting them from damage by exploiting the toughness of the metal matrix.
