Metallurgical Product Description

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-iron-based alloys. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98% (in recent years, 99.99% Si content is also included in metallic silicon), and the remaining impurities are iron and aluminum. , calcium, etc.

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

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.

Manufacture And Use

“Metal silicon” (also called industrial silicon in our country) is a product name that emerged in the mid-1960s. Its emergence is related to the rise of the semiconductor industry. The common international method is to divide commercial silicon into metallic silicon and semiconductor silicon. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The main component silicon content is about 98% (99.99% Si content is also included in metallic silicon), and the remaining impurities are iron, aluminum, calcium, etc. Semiconductor silicon is a high-purity metallic silicon used to make semiconductor devices. It is sold in polycrystalline and monocrystalline forms, the former is cheap and the latter is expensive. It is divided into various specifications due to different uses. According to statistics, in 1985, the world consumed about 500,000 tons of metallic silicon, of which about 60% was used for aluminum alloys, less than 30% was used for organic silicon, about 3% was used for semiconductors, and the rest was used for Steel smelting and precision ceramics, etc.

Applications

Silicon is widely used in smelting alloy elements and as a reducing agent in the smelting of various metals.

Silicon metal is widely used in the refractory and power metallurgical industries to improve heat resistance, wear resistance, and oxidation resistance.

Industrial silica fume is considered an alloy additive to improve the hardenability of steel in the metallurgical and foundry industries.

Mainly used in the production of alloys, polysilicons, organic silicon materials, and refractors.
