Silicon Metal Description
Silicon metal, also known as crystalline silicon or industrial
silicon, is mainly used as an additive for non-ferrous alloy.
Silicon metal is smelted from quartz and coke in an electric
furnace, with about 98% silicon. Silicon metal is mainly composed
of silicon, so it has similar properties to silicon. Silicon has
two allotropes: amorphous silicon and crystalline silicon.
Amorphous silicon is a gray-black powder, which is actually a kind
of microcrystal. Crystalline silicon has the crystal structure and
semiconductor property of diamond, with a melting point of 1410°C,
a boiling point of 2355°C, a Mohs hardness of 7; thus, it is
brittle. Amorphous silicon is chemically active and can burn
furiously in oxygen. It can react with non-metals such as halogen,
nitrogen and carbon at high temperatures, and can also react with
metals such as magnesium, calcium and iron to form silicide.
Silicon metal is usually classified according to the content of its
three main impurities such as iron, aluminum and calcium. Based on
the content of iron, aluminum and calcium, silicon metal can be
divided into different grades such as 553, 441, 421, 3303, and
