The properties of the metallic silicon are similar to those of germanium, lead and tin, and the metallic silicon has semiconductor properties. Silicon is very abundant in the earth's crust, second only to oxygen, and accounts for more than a quarter of the total weight of the crust, and exists in the form of silica or silicates. The purest silicon mineral is quartz or silica. Silicon has two allotropes, one of which is dark brown amorphous powder with active property and can be burnt in air; the other is a crystal with stable properties (crystalline silicon). Silica and quartz are commonly used in glass and other building materials, and high quality quartz is used to make alloys, metals, and single crystals.
