• Particle Sizes: 553 (coarse) and 441 (medium)
• Forms: Flakes for precise melting and dosing

• Aligns silicon input with furnace scale, reaction kinetics, and purity requirements
• Reduces oxidation loss and improves silicon recovery
• Ensures batch-to-batch consistency for steel, alloy, and electronic-grade materials

• Alloy steel and carbon steel production
• Casting and foundry operations
• Electronic materials and battery feedstock
• Specialty chemical intermediates

Silicon metal grade and purity are critical for industrial efficiency and product quality.

• 3303: Cost-effective for bulk steelmaking and standard alloy applications
• 2202: Lower impurities for casting and controlled alloys
• 1101: High-purity requirement applications such as electronics and specialty steels

Particle size and form determine oxidation behavior, melting rate, and alloying efficiency.

• Flakes: Larger surface area, faster dissolution, ideal for rapid alloying corrections
• Granules: Improved flowability, reduced dust, stable feeding for continuous or automated dosing

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

ZhenAn enforces strict screening and batch-level verification to reduce variability and ensure predictable 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

These properties ensure predictable furnace behavior, consistent alloy composition, and reliable electronic material feedstock.

Silicon metal acts as a deoxidizer and alloying regulator, affecting:

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