Polysilicon Polycrystalline Silicon

 

Polysilicon Metal refers to reclaimed or off-grade silicon materials derived from polysilicon production processes, including bottom residues, top-cut sections, and edge trims. It is mainly applied in aluminum alloy production, steel deoxidation, and other industrial silicon-consuming processes where ultra-high purity is not required.

 

 

 

 

Metallurgical and Aluminum Alloy Production

Can be used as a partial substitute feedstock in metallurgical applications where ultra-high purity silicon (e.g., electronics-grade) is not required.

 

Silicon Metal Substitution in Cost-Sensitive Processes

May replace standard silicon metal grades (such as 2202 or 1101) in non-critical alloying processes where cost optimization is prioritized over purity consistency.

 

Steelmaking Deoxidation

Can be used in selected steelmaking processes as a silicon source for deoxidation, depending on impurity tolerance of the final steel grade.
