Industrial Grade 99.8% Pure Silicon Metal Flakes & Granules ISO9001 Certified

For industrial steelmakers, alloy producers, and high-purity material processors, silicon metal is more than a raw material—it’s a process-controlling element.

Frequent operational challenges include:

• Fluctuating silicon recovery in steel deoxidation, leading to inconsistent alloy composition
• Uncontrolled oxidation losses caused by inappropriate particle size selection
• Impurity migration (Fe, Al, Ca) affecting product quality in both steel and electronic materials
• Batch-to-batch variability that complicates furnace control and dosing schedules

ZhenAn’s Industrial Grade Silicon Metal 3303 / 1101 is engineered to address these real-world challenges, ensuring consistent performance, predictable melting behavior, and minimal contamination risk.

ZhenAn supplies silicon metal in 3303 and 1101 grades, available as flakes and granules, with multi-size options 441 and 553. This allows users to:

• Align silicon input with furnace scale, reaction speed, and purity requirements
• Reduce operational variability and improve batch-to-batch consistency
• Optimize cost-efficiency without compromising downstream material quality

Target Applications:

• Alloy and carbon steel production
• Casting and foundry operations
• Electronics and photovoltaic materials
• Chemical intermediates and specialty organosilicon compounds

Each grade is designed with a specific industrial rationale, balancing cost, purity, and process tolerance.

Technical Implications:

• 3303: Optimized for metallurgical efficiency in steel and alloy systems
• 1101: Required for electronics, high-purity chemical, and photovoltaic applications where even trace impurities matter

The physical form and particle size of silicon metal directly influence oxidation rate, melting consistency, and overall yield.

• Flakes: larger surface area, faster reaction, ideal for rapid alloy adjustments
• Granules: improved flowability, reduced dust, better feeding stability in continuous processes

• 553 (Coarse): 10–100 mm, lower oxidation, higher recovery, suited for primary steelmaking and bulk alloying
• 441 (Medium): 10–50 mm, faster dissolution, more uniform distribution, preferred in casting and precision alloying

Strict screening and size control ensures predictable behavior and minimizes process deviations.

• Metallic silver-gray crystalline appearance
• Hard, brittle structure for controlled melting and handling
• Melting point: ~1414 °C
• Density: ~2.33 g/cm³
• Stable thermal and electrical conductivity

These characteristics enable predictable reactions in furnaces, controlled alloying, and reliable electronic-grade material feedstock.

Silicon metal serves as a primary deoxidizer and alloying regulator, influencing:

• Oxygen removal efficiency
• Slag-metal equilibrium
• Final steel quality and internal cleanliness

Grades 3303 and 1101, with appropriate size selection, help:

• Reduce corrective alloy consumption
• Stabilize chemical composition across multiple heats
• Improve overall furnace efficiency and process reliability

In cast iron and specialty casting:

• 441-size silicon metal provides uniform dissolution
• Consistent purity reduces inclusion and defect formation
• Enhances graphite structure and dimensional accuracy

High-purity 1101-grade silicon metal is used in:

• Polysilicon production
• Photovoltaic material preparation
• Battery and energy storage applications

Low Fe, Al, and Ca levels reduce downstream contamination, improving yield and material performance.

Industrial silicon metal supports:

• Organosilicon intermediates
• Silicone oil and rubber production
• Specialty chemical synthesis

Purity stability is critical to maintain reaction consistency and catalyst efficiency.

ZhenAn silicon metal is produced via submerged arc furnace smelting, followed by:

• Controlled solidification
• Precision crushing and screening
• Batch-level chemical verification

QA emphasizes:

• Traceable raw materials
• Consistent chemical limits
• Particle size inspection
• Optional third-party verification

This ensures long-term supply reliability, essential for EEAT-aligned industrial credibility.

• Bulk bags for steel and alloy plants
• Palletized bags for controlled dosing
• Moisture-resistant protection for long-distance shipping
• Designed for industrial-scale handling and transport

Which grade is suitable for high-purity electronic applications?
1101-grade silicon metal is preferred due to minimal Fe, Al, and Ca content.

How does particle size impact process efficiency?
Coarser sizes (553) reduce oxidation loss and improve silicon recovery, while medium sizes (441) improve melting consistency and reaction uniformity.

Can specifications be customized?
Yes. Both chemical composition and particle size distribution can be tailored to specific industrial process requirements.

Is this silicon metal suitable for both steelmaking and chemical applications?
Yes, provided the grade and particle size match the process requirements.
