Silicon metal composition is mainly silicon, so and silicon with similar properties. Silicon has amorphous silicon and silicon form two allotropes. Amorphous silicon is to black powder, in fact is also a kind of micro crystal. Crystalline silicon with diamond crystal structure and semiconductor properties, melting point ***0 ℃, boiling point ***5 ℃, density is 2.*2 ~ 2.*4 g / 3 cm, Morse hardness 7, sexual brittle. Amorphous silicon chemistry properties and lively, can be severe in oxygen combustion. It at high temperatures and halogen, nitrogen, carbon etc. Nonmetal reaction, can also with magnesium, calcium, iron and other metal effect, generating silicide. Amorphous silicon almost insoluble in including hydrofluoric acid, inorganic acid and organic acid of all, but soluble in nitric acid and hydrofluoric acid mixture. Concentrated sodium hydroxide solution can dissolve amorphous silicon, release the hydrogen. Crystalline silicon less lively, even in high temperature nor and oxygen combined, it also does not dissolve in any kind of inorganic acids and organic acid, but soluble in nitric acid and hydrofluoric acid mixture and concentrated sodium hydroxide solution.
