(1) Used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain qualified steel with chemical composition and ensure the quality of steel, deoxidation must be carried out i

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.

Ultra pure silicon (with impurities of no more than a few atoms per thousand atoms) is the most important semiconductor material, widely used in computer, microwave communication, fiber optic communic

The process flow of chemical silicon includes furnace material preparation, electric furnace melting, refining and casting of silicon, and crushing by removing slag inclusions.

The metal silicon produced in China (with a silicon content of mainly 98.5%) was originally mainly used for metallurgical purposes, while the production of chemical metal silicon (with a silicon conte

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 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 so
