Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory linings and heating elements for industrial furnaces, in wearresistant parts for pumps and rocket engines,...
puter chips, light emitting diodes (LEDs), communication technology, and radar. systems, are achieved by growing thin films of materials above a common substrate. An established method of choice for thin film growth is chemical vapor deposition. (CVD).
Silicon carbide is extremely hard, with low density, low thermal expansion and high thermal shock resistance. Not susceptible to harm by molten salts, alkalis or acids, it also displays extremely high levels of chemical inertness. Because of its superior characteristics, silicon carbide can be labeled as an engineering, technical or advanced ceramic.
Amorphous silicon carbide (a‐SiC) films, deposited by plasma‐enhanced chemical vapor deposition (PECVD), have been evaluated as insulating coatings for implantable microelectrodes. The a‐SiC was deposited on platinum or iridium wire for measurement of electrical leakage through the coating in phosphate‐buffered saline (PBS, pH ).

Chemical vapor deposition at atmospheric pressure is as old as CVD itself and, indeed, up until the late 1970s virtually all epitaxial silicon deposition was done using VD . VD is characterized by film deposition in the transportlimited regime, high gas flows, and, because vacuum equipment is not required, low equipment cost.
