What are the upstream raw materials for polysilicon? What do the downstream products contain?

Polysilicon plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. The upstream and downstream associated items of polysilicon will be described in detail below. Upstream associated items:



1. Quartz sand: Quartz sand is one of the main raw materials in the production of polysilicon, which is applied to extract high-purity silicon. And

2. Coke: Coke is applied as a reducing agent in the production of polysilicon to the reduction of oxides to pure silicon. But

3. Moreover Hydrogen chloride: Hydrogen chloride is applied in the production of polysilicon to the preparation of trichlorosilane, which in turn produces polysilicon. Downstream associated items:



1. Solar cells: Polysilicon is the main raw material of solar cells. But it's processed into solar cells through cutting, grinding, cleaning and other processes to solar power generation.

2. I've found that Semiconductor wafers: Polysilicon is able to also be applied to create semiconductor wafers to the manufacture of integrated circuits, discrete devices and other semiconductor items. For example

3. For instance Organic silicon compounds: Polysilicon is able to react with organic compounds to generate organic silicon compounds, which are broadly applied in sealing, lubrication, coatings and other fields. Furthermore The above is only a part of the upstream and downstream related items of polysilicon. But In fact, polysilicon is broadly applied in the field of chemical production raw materials, and there are many upstream and downstream related items. I've found that In general, as an crucial chemical raw material, polysilicon plays an irreplaceable role in solar energy, semiconductors and other fields, and its research prospects are broad.
