Premium Silicon Metal 1101/3303 | 99.8% Purity Flakes & Granules
For steel producers, alloy manufacturers, and battery or electronic material buyers, silicon metal performance is judged by how predictably it behaves in real processes. ZhenAn's Premium Silicon Metal 1101/3303 addresses operational challenges through controlled purity, defined particle form, and application-oriented grading.
Process Challenges in Industrial Silicon Use
- Inconsistent silicon recovery during deoxidation
- Excessive oxidation loss from unsuitable particle size
- Metallic impurity carryover affecting materials
- Batch variability complicating process control
Product Specifications & Applications
This product range combines grade selection (1101 and 3303), physical forms (flakes and granules), and size control (441 and 553) to align silicon input with furnace scale, reaction speed, and impurity tolerance.
Primary Applications
- Alloy steel and specialty alloy production
- Electronics and battery-related material processing
- Chemical synthesis requiring stable silicon feedstock

Grade Selection Guidance
3303: Designed for metallurgical systems balancing silicon yield, cost efficiency, and minor impurity tolerance
1101: Selected when impurity-sensitive reactions or downstream purification costs dominate decision-making
Physical Forms: Flakes vs Granules
Silicon Flakes
- Larger surface area for faster dissolution
- Accelerated reaction rates
- Ideal for rapid alloy adjustment and controlled additions
Silicon Granules
- Improved flowability for automated systems
- Reduced dust generation
- Stable feeding in continuous processes
Particle Size Control
553 Size (Coarse Range: 10–100 mm)
- Slower oxidation rate
- Higher recovery in medium and large furnaces
- Common in steelmaking and bulk alloy additions
441 Size (Medium Range: 10–50 mm)
- Faster melting and uniform distribution
- Preferred for cast iron correction and precision alloying
- Stabilizes silicon input per ton of metal produced
Physical Properties
- Metallic silver-gray crystalline appearance
- Hard, brittle structure
- Melting point: ~1414°C
- Density: ~2.33 g/cm³
- Stable thermal and electrical conductivity
Application Performance
Alloy & Steel Manufacturing
Functions as both deoxidizing agent and chemical composition regulator. Using appropriate grades and sizes improves oxygen removal efficiency, reduces corrective additions, and enhances batch consistency.
Electronics & Battery Materials
High-purity 1101 grade serves as upstream material for polysilicon production, electronic processing, and advanced energy systems. Low Fe and Al levels reduce contamination risk.
Chemical Industry Applications
Used as feedstock for organosilicon intermediates, silicone rubber, fluid production, and specialty chemical synthesis. Purity stability is critical for reaction yield and product quality.
Quality Assurance & Manufacturing
Produced via submerged arc furnace smelting with controlled cooling, crushing, screening, and batch classification. Quality assurance includes raw material traceability, batch-level chemical verification, particle size inspection, and optional third-party testing.
Packaging & Handling
- Bulk packaging for steel and alloy plants
- Palletized packaging for controlled dosing
- Moisture-resistant protection
- Designed for efficient loading and international shipment
Technical Considerations
Is 1101 necessary for battery or electronics applications?
Yes. Higher purity reduces impurity-driven defects and purification costs.
Does particle form affect silicon recovery?
Yes. Granules improve feeding stability, while flakes accelerate reaction speed.
Which size is better for large furnaces?
553 size is generally preferred due to lower oxidation loss.
Can specifications be adapted to specific processes?
Yes. Both chemical limits and particle characteristics can be adjusted.
