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.
