Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide (also known as carborundum) and boron carbide are very hard materials and refractory. Both materials are important industrially.

Products such as pure silicon are made via the Lely process, in which the carbon powder is sublimated in argon and then redeposited. Types. Examples of different types of carbides include boron carbide, silicon carbide, and tungsten carbide (WC). Boron carbide (B 4 C) has higher hardness than alumina
Silicon - University of Denver
Nov 30, 2002· Silicon is an word known to the public, at least in the phrase "Silicon Valley," and is associated with computers, although the public probably does not know what a chemical element is, or how silicon is used in computers, or where it comes from, or how it behaves. The earth is constructed of silicon, and we use it every day in the form of
How to drive SiC MOSFET…. The right way !! | TI Video
Silicon carbide is used to manufacture the trauma plates inside ballistic vests, taking advantage of its diamond-like strength. Carbon ceramic, which is essentially silicon carbide, is used to develop car disk brakes. Silicon carbide is also used in steel manufacturing, due to its very high melting point and high thermal conductivity.
