Metallurgical Product Description

Metallic silicon is processed from high-quality industrial silicon and comes in a full range of varieties. Used in electronics, metallurgy, chemical, and other industries. It is a silver-gray or dark gray powder with a metallic luster, high melting point, good heat resistance, high resistivity, and excellent antioxidant properties. It is called “industrial glutamic acid” and is an indispensable basic raw material for high-tech industries.

Product Parameters

Specification granularity: natural block, 10-100mm, 10-60mm, 3-10mm, 1-3mm, 0-1mm, or customized according to customer requirements.

Packaging: Ton bag packaging (1000kg/bag) or customized according to customer requirements.

Product Advantages

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 the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.

Manufacture And Use

Silicon is used in large quantities to smelt ferrosilicon alloy as an alloying element in the steel industry and as a reducing agent in the smelting of many metals. Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon.

Silicon is the raw material for ultrapure silicon in the electronics industry. Electronic devices made of ultrapure semiconductor single crystal silicon have the advantages of small size, lightweight, good reliability, and long life. High-power transistors, rectifiers, and solar cells made from silicon single crystals doped with specific trace amounts of impurities are better than those made from germanium single crystals.

Research on amorphous silicon solar cells has progressed rapidly, and the conversion rate has reached more than 8%. The maximum operating temperature of the silicon molybdenum rod electric heating element can reach 1700°C, and its resistance is not easy to age and has good anti-oxidation properties.

Trichlorosilane produced from silicon can be used to prepare hundreds of silicone lubricants and waterproofing compounds. In addition, silicon carbide can be used as an abrasive, and quartz tubes made of high-purity silicon oxide are important materials for high-purity metal smelting and lighting fixtures.

Applications

It is widely used in refractory materials and powder metallurgy industries to improve its heat resistance, wear resistance, and oxidation resistance.

In the field of silicone chemical industry, industrial silicon powder is the basic raw material of silicone polymers.

Industrial silicon powder is sublimated into single-crystal silicon, which is an important raw material for integrated circuits and electronic components and is widely used in high-tech fields.

In the metallurgy and foundry industries, industrial silicon powder is used as an iron-based alloy additive and an alloying agent for silicon steel to improve the hardenability of steel.

These are used in high-temperature material production to make enamels and pottery. These also serve the needs of the semiconductor industry by producing ultra-pure silicon wafers.
