Industrial silicon, also known as metallic silicon or crystalline silicon, the English name is Silicon Metal, is composed of silica (SiO2 ≥ 99.2%, usually quartz stone or pebbles) and carbonaceous reducing agents (petroleum coke, washed coal, charcoal and other reducing agents) in The product formed by high-temperature reaction smelting in the submerged arc furnace contains about 98% of the main component silicon, and the remaining impurities are iron, aluminum, calcium, etc. Its properties are similar to those of germanium, lead, and tin, and can be used in semiconductors, etc.

It can currently be used in the production of organic silicon, polycrystalline silicon, aluminum alloys and other chemical and electronic industries. At the same time, the downstream application fields have penetrated into the national defense industry, information industry, new energy and other related industries. It has a special position in my country’s economic and social development. It is a new energy, It is an important material that is indispensable for the development of the new materials industry, and the industry has broad prospects.
