Application Performance
Steel & Alloy Production
Silicon metal acts as a deoxidizer and alloying regulator. Using 3303 or 2202 with correct size selection improves silicon recovery per ton, batch-to-batch composition stability, and alloying efficiency.
Casting & Foundry
Medium grain 441 ensures uniform dissolution, reduced impurity carryover decreases defect formation, and optimizes graphite structure and dimensional accuracy.
Electronics & Renewable Energy
High-purity 1101-level silicon metal is critical for polysilicon and photovoltaic materials, battery material feedstock, and minimizing downstream contamination.
Chemical Industry
Supports organosilicon intermediates, silicone oils and rubbers, and specialty chemical synthesis. Purity stability protects catalysts and ensures reaction consistency.
Manufacturing & Quality Assurance
Produced via submerged arc furnace smelting, followed by controlled solidification, precision crushing and screening, and batch-level chemical verification. Quality control emphasizes traceable raw material sourcing, consistent chemical limits, particle size inspection, and optional third-party verification.
Packaging & Handling
- Bulk bags for steel and alloy plants
- Palletized packaging for precise dosing
- Moisture-resistant protection for transport
- Suitable for industrial-scale handling and shipping
