What Is Silicon Metal Powder Used For? ‌

‌Batteries‌: Anode material in lithium-ion batteries (high-purity nano-powder).

‌Refractories‌: Heat-resistant linings for kilns/furnaces.

‌Silicones‌: Raw material for silicone polymers (sealants, lubricants).

‌Metallurgy‌: Alloy additive in aluminum/steel production.

‌Metallurgical-grade silicon (98.5% purity)‌: ‌1,800–1,800–2,500/ton‌ (Q2 2024, China spot price) 📉.

‌Semiconductor-grade polysilicon‌: ‌20,000–20,000–50,000/ton‌ (high-purity for solar/chips).
Prices fluctuate with energy costs and China's production quotas.

‌2,100–2,100–2,400/ton‌ (current global benchmark).

‌Grade 441 specs‌: 99% Si, ≤0.4% Fe, ≤0.4% Al, ≤0.1% Ca.
Commonly used in aluminum alloys and silicones.

‌Aluminum alloys‌: ~55% of global use (e.g., autos/aerospace parts).

‌Silicones‌: ~35% (sealants, medical devices).

‌Semiconductors‌: ~7% (purified to 9N for chips/solar cells).

‌Steel deoxidation‌: Removes oxygen during steelmaking.

‌Cast iron‌ (1–3% Si):

Promotes ‌graphite formation‌, improving machinability.

Boosts ‌strength‌ and ‌heat resistance‌ (e.g., engine blocks).

‌Electrical steel‌ (up to 6.5% Si):

Reduces ‌core losses‌ by 90% in transformers/motors.
