Metallic silicon
Product Introduction:
Metallic silicon, also known as crystalline silicon or industrial silicon, is a product produced by smelting quartz and coke in an electric furnace. The main component of silicon is about 98%, with other impurities such as iron, aluminum, and calcium.
The classification of metallic silicon is usually based on the content of the three main impurities, iron, aluminum, and calcium, contained in the composition of metallic silicon. According to the content of iron, aluminum, and calcium in metal silicon, it can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, etc.
Nature:
Silicon is one of the semi metals, formerly known as "silicon". The melting point is 1420 ℃ and the density is 2.34g/cm3. Hard and brittle in texture. Insoluble in acids 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 and accounting for more than a quarter of the total weight of the Earth's crust. It exists in the form of silica or silicates. The purest silicon mineral is quartz or silica. Silicon has two types of allotrope: one is a dark brown amorphous powder with active properties that can burn in air; The other type is stable crystals (crystalline silicon). General silica and quartz are used for glass and other building materials, while high-quality quartz is used for making alloys, metals, and single crystals
Purpose:
Silicon is extensively used for smelting into ferrosilicon alloys as an alloying element in the steel industry, and as a reducing agent in many metal smelting processes. Silicon is also a good component in aluminum alloys, and the vast majority of cast aluminum alloys contain silicon. Silicon is the raw material of ultrapure silicon in the electronic industry. Electronic devices made of ultrapure semiconductor monocrystalline silicon have advantages such as small volume, light weight, good reliability, and long lifespan.
