Products Description
Silicon Metal is a refined form of elemental silicon produced by reducing high-grade quartz with carbon materials in electric arc furnaces. Known for its silvery-gray metallic appearance, high chemical stability, and low impurity levels, silicon metal is an essential raw material for aluminum-silicon alloys, silicone chemicals, semiconductors, and photovoltaic cells. Our products are manufactured under strict quality control to meet diverse industrial needs.

Packaging: Jumbo bags (1MT), 25kg bags, or per customer request
How Do You Store Silicon Metal Safely?
To maintain its quality and prevent contamination:
Dry Environment: Store in a moisture-free area to avoid oxidation and lump degradation
Ventilation: Keep in a well-ventilated warehouse to prevent condensation
Clean Surface: Avoid contact with soil, oil, or other impurities
Stacking Method: Use pallets or wooden planks to keep bags off the ground
Avoid Impact: Prevent excessive handling or crushing to maintain particle integrity
What Packaging Options Are Available for Silicon Metal Shipments?
We offer flexible packaging to suit different shipment sizes and customer needs:
1MT Jumbo Bags: Ideal for bulk shipments, moisture-proof and UV-protected
25kg PP/PE Bags: Suitable for smaller orders or precision applications
Customized Packaging: Available with company logos, color printing, or specific labeling
Lined Bags: Inner plastic liners for extra moisture protection during sea transport
