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 Introduction

Properties of metallic silicon Production process and flow

Metallic silicon has semiconductor properties. It is insoluble in acid at room temperature and easily soluble in alkali. Metallic silicon has a dark gray luster, high melting point, good heat resistance, high resistivity, and high antioxidant effect.

Production method and process flow
The main raw materials are quartz sand and coke, of which quartz sand provides silicon dioxide and coke is used as a reducing agent.
Through arc furnace smelting, the carbon in the coke reacts with the silicon dioxide in the quartz sand to produce metallic silicon and carbon monoxide.
During the refining and purification process, specific additives are added to react with impurity elements to produce easily separated compounds, and then the impurities are separated through physical operations such as filtration and distillation.
