Premium Silicon Metal 1101 / 3303 | Multi-Size Industrial Si for Steelmaking, Chemical Applications & Solar Panels | 2202 / 553 / 441
Industrial Challenge: Silicon Metal as a Critical Process Component
Silicon metal is a key factor in industrial efficiency and product quality, not just a raw material. Steelmakers, alloy producers, and renewable energy material manufacturers often face:
- Variability in deoxidation and alloying efficiency despite using standard grades
- Oxidation and material loss due to unsuitable particle sizes
- Trace impurities (Fe, Al, Ca) affecting steel, chemical intermediates, or photovoltaic feedstock
- Batch-to-batch inconsistencies complicating furnace operations and dosing schedules

Industrial Implications
- 1101: High-purity applications such as electronics, batteries, and solar-grade materials
- 3303: Cost-effective for bulk steelmaking and standard alloy production
- 2202: Controlled impurity grade for casting and chemical processes
Particle Form & Size Considerations
Particle size and form are critical for melting consistency, oxidation control, and alloying efficiency.
Flakes vs Granules
- Flakes: Larger surface area, faster dissolution, ideal for rapid alloying or chemical reactions
- Granules: Controlled flow, reduced dust, and stable feeding in automated or continuous systems
Size Selection
- 553 (Coarse): 10–100 mm; slower oxidation, higher silicon recovery, ideal for primary steelmaking
- 441 (Medium): 10–50 mm; faster dissolution, uniform distribution, preferred for casting, chemical, and solar feedstock
ZhenAn implements strict size screening and batch-level verification to ensure consistent industrial performance.
Material Properties
- 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 furnace behavior, stable alloy composition, and reliable feedstock for chemical and renewable energy applications.
