Key Advantages
Cost-Effective Silicon Source
Compared with high-grade silicon materials, silicon slag provides a more economical option for applications where strict purity requirements are not required.
Flexible Grade Selection
Different silicon content grades are available, including 45%, 50%, 55%, 60%, and 65% Si slag.
Supporting Circular Utilization
The recovery and reuse of silicon content help improve resource utilization in silicon production.
Applications
Silicon Recovery
Silicon slag contains a certain amount of recoverable silicon, which can be processed for industrial silicon recovery and resource reuse.
Steelmaking Deoxidizer
The silicon content in silicon slag can participate in oxygen removal during steelmaking, providing an economical option for deoxidation applications.
Metallurgical Reducing Agent
Silicon slag can be used as a reducing material in certain metallurgical processes, including stainless steel-related production applications.
Foundry Applications
It can also be used in foundry processes requiring silicon-containing materials for iron and alloy treatment.
