1.Application of industrial silicon furnace:
Industrial silicon, also known as crystalline silicon or industrial silicon. The main use of industrial silicon is as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for strict requirements of silicon steel, as well as a deoxidizer for smelting special steel grades and non-ferrous alloys. After a series of industrial processes, industrial silicon can be processed into single crystal silicon for use in the electronics industry.
Industrial silicon is widely used in the preparation of alloys, the production of high-purity semiconductor materials, the production of solar cells, the production of temperature resistant materials, and organic silicon. In today's society, it has entered the era of informatization and has been widely used in scientific research, as well as various fields such as electrical, aviation, machinery, chemical, pharmaceutical, and national defense in industrialized countries.
