SPECIFICATIONS

Chemical Composition: Polycrystalline Silicon (poly-Si), a multi-crystalline form of silicon, primarily composed of silicon with minor impurities controlled during the Siemens process.

Forms:

  • Ingots: Large blocks for slicing into wafers.

  • Wafers: Thin slices for solar cells and chips.

  • Granules: Small particles for metallurgical use.

  • Chunks: Irregular pieces for industrial processing.

Weights:

  • Ingots: 10-100 kg per unit.

  • Wafers: 0.01-0.5 kg per batch.

  • Granules: 25-250 kg per bag.

  • Chunks: 1-20 kg per unit.

Purity Levels:

  • 6N (99.9999%): Standard purity for solar-grade silicon.

  • 7N (99.99999%): High purity for electronics.

  • 8N (99.999999%): Ultra-pure for advanced semiconductors.

  • 9N (99.9999999%): Maximum purity for niche applications.

Doping Types:

  • Boron-Doped (p-type): For positive charge carriers.

  • Phosphorus-Doped (n-type): For negative charge carriers.

  • Undoped: Raw silicon for custom doping.

  • Antimony-Doped (n-type): Enhanced conductivity for specific uses.

Sizes:

  • Ingots: 100-300mm width, 100-500mm length, 50-200mm height.

  • Wafers: 100-300mm diameter, 0.1-1mm thickness.

  • Granules: 1-5mm particle size.

  • Chunks: 10-100mm max dimension, irregular shapes.

Certificates:

  • RoHS Compliance: Ensures no hazardous substances, safe for electronics and EU markets.

  • ISO 9001: Guarantees consistent quality management throughout production.

  • EN 10204 3.1: Confirms compliance with order specs, backed by independent test results.
