Silicon is one of the semi-metals, formerly known as "silicon". The melting point is 1420°C and the density is 2.34g/cm3. Hard and brittle. Insoluble in acid at room temperature, easily soluble in alkali.
The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties. Silicon is extremely abundant in the earth's crust, second only to oxygen, accounting for more than a quarter of the total weight of the earth's crust, and exists in the form of silica or silicate.
The purest silicon mineral is quartz or silica. Silicon has two allotropes: one is a dark brown amorphous powder, which is reactive and can burn in the air; the other is a stable crystal (crystalline silicon). Generally, silica and quartz are used in glass and other building materials, and high-quality quartz is used to make alloys, metals and single crystals.
