What role do vacuum pumps play in the production of monocrystalline silicon and polycrystalline silicon?
Thread Content
Dear experts, why are vacuum pumps needed in the production of solar energy materials such as monocrystalline silicon and polycrystalline silicon? What is its main function?
Different places have different reasons for needing vacuum pumps. The silicon industry involves many process conditions, such as water, electricity, and gas as utility media, as well as things like scrubbers and chlor-alkali processes
Customers in the photovoltaic industry generally still prefer to use imported dry pumps
Silicon monocrystalline and polycrystalline sintering furnaces use vacuum for crystal pulling; this is primarily to prevent impurity contamination and reactions with other gases, thereby improving the purity of the crystals produced
