For the physical property, the silicon carbide is very hard and it has a very high melting point. (Matindale). The PV cell can last for 25 years and it is one of the most relevant energy resources to use. Also the semiconductor is only consisted of silicon carbide
Inorganic fibers - /a>
Their diameter changes from 5 to 15 nm, but other ones are much thicker, like the ones got through vapor deposition on the fibers, such as borate fibers and silicon carbide fibers (100-150 n). The diameter of the fiber is critical compared to its resistance: like all fragile materials their resistance increases when their transversal size reduces.
