Silicon carbide | Cerámica Wiki | Fandom
Silicon carbide does not melt at any known pressure. It is also highly inert chemically. There is currently much interest in its use as a semiconductor material in electronics, where its high thermal conductivity , high electric field breakdown strength and high maximum current density make it more promising than silicon for high-powered devices. 
New processing methods to produce silicon carbide …
Abstract For inert matrix fuels, SiC and BeO represent two possible matrix phase compounds that exhibit very high thermal conductivity, high melting points, low neutron absorption, and reasonably high radiation stability. BeO is chemically compatible with UO 2, PuO 2 and Zircaloy to very high temperatures, but SiC reacts with all three at somewhat lower temperatures.

Silicon Carbide in Microsystem Technology — Thin Film …
10/11/2014· Silicon and silicon carbide have also the same native insulating oxide that might be exploited for the processing and fabriion of Si-SiC-based electronic devices. The silicon lattice constant is 5.43 Å, while in 3C-SiC it is 4.36 Å, which results in a lattice mismatch of approximately 20% and it can lead to a highly defective epitaxial film, which can be detrimental for electronic devices.
