Metallic silicon, also known as crystalline or industrial silicon, is mainly used as an additive for non-iron-based alloys. Industrial silicon is also used as an alloying agent for silicon steel with strict requirements and as a deoxidizer for smelting special steels and non-ferrous alloys. After a series of processes, industrial silicon can be drawn into single-crystal silicon for use in the electronics industry.

Metal silicon product properties:

The main component of metallic silicon is silicon, so it has similar properties to silicon. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.

Metal silicon product categories:

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

Product Parameters

Product Advantages

The main component of metallic silicon is 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 a microcrystal. Crystalline silicon has the crystal structure and semiconductor properties of diamond, with a melting point of 1410°C, a boiling point of 2355°C, Mohs hardness of 7, and brittleness. Amorphous silicon is chemically active and can burn violently in oxygen. It reacts 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 silicides. Amorphous silicon is almost insoluble in all inorganic and organic acids, including hydrofluoric acid, but is soluble in a mixed acid of nitric acid and hydrofluoric acid. Concentrated sodium hydroxide solution can dissolve amorphous silicon and release hydrogen gas. Crystalline silicon is relatively inactive and does not combine with oxygen even at high temperatures. It is not soluble in any inorganic acid or organic acid but is soluble in mixed acids of nitric acid hydrofluoric acid and concentrated sodium hydroxide solution.

Manufacture And Use

Silicon is one of the semi-metals, formerly known as “silicon”. The melting point is 1420°C and the density is 2.34 grams per cubic centimeter. 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.

Applications

Metallic silicon is used to produce organic silicon, prepare high-purity semiconductor materials, and prepare alloys for special purposes.

(1) Produce silicone such as silicone rubber, silicone resin, and silicone oil.

(2) Manufacturing high-purity semiconductors.

(3) Prepare alloy.
