What are the cleanliness requirements for polysilicon production?
The cleanliness of the system largely determines the quality grade of the product
Industrial-grade dust-free versions are very expensive. So it’s good if the visual appearance is clean.
It has to be said that there are reasons why it’s difficult for China to produce electronics-grade products
Polysilicon production workshops require a clean environment at the 100,000-class standard; however, during furnace disassembly and cleaning of the chassis, large amounts of silicon powder are released into the air. As long as the material pipelines remain uncontaminated, electron-grade polysilicon can be produced.
