Silicon - Academic Dictionaries and Encyclopedias

Silicon is a semiconductor, readily either donating or sharing its four outer electrons, allowing for many different forms of chemical bonding. Even though it is, similar to carbon, a relatively inert element, silicon still reacts with halogens and dilute alkalis, but most acids (except for some hyper-reactive coinations of nitric acid and hydrofluoric acid) have no known effect on it.

Anatomy of an abrasive cutting machine

Nonreinforced abrasive wheels—which typically are used in abrasive cutting machines—are made with aluminum oxide, silicon carbide, zirconia, diamond, and cubic boron nitride. Of these, only aluminum oxide and silicon carbide are used for cutting ferrous and nonferrous metals and alloys.
