Almost pure silicon piece wire wrappedSilicon is the seventh most abundant element in the universe and the second most abundant element in the earth's crust. Today, silicon is produced by heating sand (SiO 2) with carbon to temperatures approaching 2200°C. Two allotropes of silicon exist at room temperature: amorphous and crystalline. Amorphous appears as a brown powder while crystalline silicon has a metallic luster and a grayish color.Silicon is present in the sun and stars and is a principal component of a class of meteorites known as aerolites. It is also a component of tektites, a natural glass of uncertain origin. Silicon makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, being exceeded only by oxygen. Silicon is not found free in nature, but occurs chiefly as the oxide and as silicates. Sand, quartz, rock crystal, amethyst, agate, flint, jasper, and opal are some of the forms in which the oxide appears. Granite, hornblende, asbestos, feldspar, clay, mica, etc. are but a few of the numerous silicate minerals.
Silicon is prepared commercially by heating silica and carbon in an electric furnace, using carbon electrodes. The Czochralski process is commonly used to produce single crystals of silicon used for solid-state or semiconductor devices.Silicon is a semiconductor. Unlike most metals, silicon is better at conducting the hotter it gets. Pure Silicon is a good conductor and a good insulator.Silicon, metal, wire, glass crystals, polished stones. The materials are all natural and will do well in an outside environment.
