Production Process

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 rich in resources 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 silicon dioxide or silicate. The purest silicon mineral is quartz or silica.

Silicon has two allotropes: one is dark brown amorphous powder, which is active and can burn in air; the other is stable crystal (crystalline silicon). Generally, silica and quartz are used for glass and other building materials, and high-quality quartz is used for making alloys, metals and single crystals

Products Description

The classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in metal silicon. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and so on.

Industrially, metallic silicon is usually produced by reducing silicon dioxide with carbon in an electric furnace. Chemical reaction equation: SiO2 + 2C → Si + 2CO The silicon purity obtained in this way is 97~98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with a purity of 99.7~99.8%.

The metal silicon component is mainly 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.
