Discussion on the treatment method of waste silicon material by silicon material
- Nov 23, 2018 -

The electronic grade waste silicon scrap or block material that meets the silicon material condition is used as a raw material and is returned to the furnace for use. There must be a series of treatments before the furnace is returned, and there are different treatment methods depending on the two types of waste silicon materials. The details are as follows for everyone!

1. Treatment of raw waste silicon material: properly clean and dry.

2. Processing of finished waste silicon wafers: different treatments are carried out according to the waste materials processed to different process steps, and the original silicon materials are restored by a series of chemical methods (the same as the direct processing of the finished waste silicon whole sheet). The original appearance can be returned to the furnace as a raw material for solar grade silicon wafers.
