Premium Silicon Metal 553 / 3303 | High Purity 99.9% Si for Alloy Steel, Casting, and Renewable Energy | 2202 / 1101 / 441 Sizes

In industrial operations, silicon metal is often underestimated, yet it directly impacts yield, product quality, and operational efficiency.

Steelmakers, alloy producers, and battery or photovoltaic material manufacturers frequently encounter:

• Variability in steel deoxidation and alloying performance
• Oxidation losses caused by mismatched particle sizes
• Trace impurities (Fe, Al, Ca) affecting mechanical, chemical, or electronic-grade products
• Batch inconsistency that complicates furnace control and dosing precision

ZhenAn's Premium Silicon Metal 553 / 3303 is designed to stabilize process performance, reduce material loss, and improve product consistency, offering a strategic advantage in high-purity industrial operations.

ZhenAn provides silicon metal in 3303 grade, with 553 coarse particle distribution and optional 2202 / 1101 / 441 size variations, suitable for flakes or granules.

• Aligns silicon input with furnace size, reaction rate, and purity requirements
• Reduces oxidation loss and improves silicon recovery
• Ensures batch-to-batch consistency across steelmaking, casting, and chemical processes

• Alloy and carbon steel production
• Casting and foundry operations
• Renewable energy materials (polysilicon, solar-grade silicon)
• Specialty chemicals and organosilicon intermediates

Silicon metal grade and purity significantly affect process outcomes.

• 3303: Cost-effective for bulk steelmaking and standard alloy production
• 2202: Cleaner profile for controlled alloys and casting
• 1101: High-purity applications in electronics, batteries, and renewable energy

Particle size and form are crucial for melting consistency, oxidation control, and process efficiency.

• Flakes: High surface area, faster dissolution, ideal for rapid alloying adjustments
• Granules: Controlled flow, reduced dust, suitable for continuous or automated dosing

• 553 (Coarse): 10–100 mm; reduces oxidation, improves silicon recovery, ideal for primary steelmaking
• 441 (Medium): 10–50 mm; faster dissolution, uniform distribution, preferred for casting and secondary alloying

ZhenAn applies strict size screening and batch verification to maintain consistent industrial performance.

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

Ensures predictable reactions in furnaces, stable alloy composition, and reliable feedstock for chemical and electronic materials.

Silicon metal acts as deoxidizer and alloying regulator, influencing:

• Oxygen removal efficiency
• Slag-metal balance
• Final steel strength and internal cleanliness

• 553-size 3303 / 2202 for primary steelmaking improves silicon recovery and batch stability
• 1101-grade ensures low-impurity alloying for specialty steels

• 441 particle size ensures uniform dissolution
• Minimizes impurity carryover, reducing defects
• Optimizes graphite structure, fluidity, and mechanical properties

• High-purity 1101-grade silicon for polysilicon and solar materials
• Reduces downstream purification and contamination risk
• Improves yield and quality of battery and photovoltaic materials

• Supports organosilicon intermediates, silicone oils, and specialty chemical production
• Maintains catalyst efficiency and consistent reaction yields due to controlled impurity levels

Produced via submerged arc furnace smelting, followed by:

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

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

This guarantees reliable, predictable supply, essential for industrial EEAT credibility.

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

1101-grade silicon metal is recommended due to minimal Fe, Al, and Ca content.

Yes. Coarse (553) reduces oxidation and improves recovery; medium (441) enhances dissolution uniformity.

Yes. Both chemical composition and particle size can be customized to match process requirements.

Yes, when particle size and purity grade are aligned with the application.
