Description

Silicon metal is also known as crystalline silicon or industrial silicon, it is mainly used as an additive for non-ferrous alloys. Silicon is a non-metallic element, gray, metallic, hard and brittle. The content of silicon accounts for about 26% of the mass of the earth's crust; The atomic weight is 28.80; The density is 2.33g/m3; Melting point 1410 ° C; The boiling point is 2355 ° C; The resistivity is 2140 Ω m。

Grades:

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

By-products:

Silica fume, also known as micro silica fume and its scientific name is silica fume, is formed by collecting and treating the smoke and dust escaping with the waste gas in the process of smelting industrial silicon and ferrosilicon in industrial electric furnace at high temperature. It is widely used in refractory and concrete industries.

Purpose:


1. In the chemical industry, used to produce organic silicon. Silicone material has high and low temperature resistance, moisture resistance, insulation, aging resistance, physiological inertia and other excellent performance, widely used in textile, electronic appliances, petroleum, chemical and other fields.

2. Used to produce polysilicon. Polycrystalline silicon is the raw material for the preparation of monocrystalline silicon and solar cells, which is the cornerstone of the global electronics industry and photovoltaic industry.

3.Used to produce alloy. Silicon for silicon aluminum alloy: silicon aluminum alloy has low density, low thermal expansion coefficient, good casting performance and wear resistance, and is commonly used in the production of automobile parts and real estate industry.
