Metallurgical Grade Silicon

Our metallurgical-grade silicon offers core advantages of exceptional purity, consistent particle size, and stable chemical composition, strictly adhering to international standards and customized client requirements.

• High Purity Standard: Typical silicon (Si) content ≥ 98.5%. Advanced smelting processes effectively minimize key impurities.
• Key Impurity Control:
• Iron (Fe): < 0.5%
• Aluminum (Al): < 0.5%
• Calcium (Ca): < 0.3%
• Physical Form: Available in standard lumps (10-100mm), custom-sized crushed blocks, and particle sizes tailored to customer specifications. Products undergo rigorous cleaning for surface purity and low dust content.
• Packaging: Supplied in 1-ton flexible intermediate bulk containers (FIBC) or 25kg woven bags, featuring moisture-proof and contamination-resistant properties for safe and convenient transportation. 

Our metallurgical-grade silicon serves as an indispensable additive in the following critical industries:

1. Aluminum-silicon alloy production: As a primary alloying element, it significantly enhances the fluidity, strength, heat resistance, and corrosion resistance of aluminum alloys. Widely used in automotive manufacturing (engine components, wheel hubs), aerospace, and structural building components.
2. Silicon-Based Chemical Feedstock: Serves as the starting material for producing organosilicon compounds (silicone oils, silicone rubbers, silicone resins) and high-purity polysilicon, forming a vital source for the photovoltaic solar and semiconductor supply chains.
3. Steel Smelting: Functions as an efficient deoxidizer and alloying agent, improving steel quality.
4. Other Applications: Includes high-temperature refractory materials and the preparation of electronic-grade silicon micropowder.
