Properties of silicon

Weden Metal Co.,Limited | Updated: Apr 21, 2017

Silicon is one of the semi metals, the old is called "Silicon". The melting point is 1420 ℃, the density is 2.34 grams per cubic centimeter. The quality is hard and brittle. Insoluble in acid at ambient temperature, soluble in alkali. The properties of silicon metal are similar to germanium, lead and tin, with semiconductor properties. Silicon in the Earth's crust is abundant resources, second only to oxygen, the Earth's total weight of one-fourth more, in the form of silica or silicate. The purest silicon minerals are quartz or silica. Silicon has two kinds of allotrope: a dark brown amorphous powder, lively in nature, can burn in the air; the other is a stable crystalline crystal (crystalline silicon). General silica and quartz for glass and other building materials, high-quality quartz for the fabrication of alloys, metals and monocrystalline
