1. Procurement Needs: Why Silicon Metal is Essential

Silicon metal (Si) is a key raw material for multiple industries due to its:

Key Applications

  • Aluminum Alloys (75% of demand) – Enhances strength & fluidity
  • Silicones & Chemicals – Used in sealants, lubricants, and resins
  • Solar Panels & Electronics – High-purity Si (99.99%) for PV cells & semiconductors
  • Steel & Foundry – Improves deoxidation and alloy properties

Common Grades & Specifications

Grade Si Content Impurities (Max) Primary Use
Si 98% 98-98.5% Fe 0.5%, Al 0.5%, Ca 0.3% Aluminum alloys, chemicals
Si 99% 99-99.5% Fe 0.4%, Al 0.4%, Ca 0.2% Solar-grade silicon, silicones
Si 99.5%+ ≥99.5% Fe 0.2%, Al 0.2%, Ca 0.1% Electronics, polysilicon

Particle Sizes: 10-100mm, 0-3mm, 3-10mm (customizable)

2. Industry Research: Silicon Metal Market Trends

The global silicon metal market is projected to grow at 5.2% CAGR (2024-2030) driven by:

Key Demand Drivers

  • Solar Energy Boom – Polysilicon demand for PV panels
  • Electric Vehicles (EVs) – Lightweight aluminum-silicon alloys
  • Electronics Expansion – Semiconductor & chip manufacturing
  • Green Aluminum – Low-carbon smelting requires high-purity Si

Regional Insights

  • China dominates production (~70% of global supply)
  • Europe & North America prioritize high-purity Si for tech applications
  • India & Southeast Asia – Fastest-growing consumers for alloys & solar

3. Procurement Guide: How to Choose Silicon Metal

1. Select the Right Grade

  • Si 98% – Cost-effective for aluminum alloys
  • Si 99% – Ideal for solar & silicones
  • Si 99.5%+ – Essential for semiconductors

2. Check Chemical Composition

  • Low Fe, Al, Ca – Critical for high-purity applications
  • Trace Elements – Phosphorus, boron affect conductivity

3. Verify Physical Properties

  • Particle Size – Affects melting efficiency
  • Lump vs. Powder – Powder for chemical reactions, lumps for smelting

4. Assess Supplier Reliability

  • Production Capacity – Avoid shortages
  • Certifications – ISO, RoHS, or customer-specific specs
  • Packaging – Moisture-proof for long-distance shipping
