Polycrystalline Silicon
Fengyang Metallurgy: The Energy Wizard – Powering Your Green Future
Polycrystalline Silicon (poly-Si)
I'm the Energy Wizard-Ignite the World with Pure Silicon Power!
Greetings! I'm Fengyang Metallurgy's Polycrystalline Silicon (poly-Si), a metallic marvel born from pure silicon crystals. As the "energy heart" of photovoltaic cells and semiconductor chips, I boast ultra-high purity (up to 99.9999%) and semiconductor-grade performance. My role? To transform sunlight into electricity and fuel cutting-edge electronics-s sustainably and efficiently!
Why Choose Polycrystalline Silicon (poly-Si)?
Efficiency Champion – Balancing Performance and Cost!
- Pure & Stable: Tolerate extreme temperatures (1410°C) and ultra-low impurities (Fe ≤0.15%, P ≤30ppm), ensuring solar cells last longer.
- Light-to-Energy Magic: Convert 15%-20% of sunlight into electricity-fuelling global decarbonization.
- Cost-Effective Innovation: Master both the Modified Siemens Process (high purity) and Silicon Hydride Fluidized Bed Process (70% energy savings), making green energy affordable for all.
The Specifications of Polycrystalline silicon
The Purest Protector – Impurities? Not in My Vocabulary!
Chemical Composition
| Element | Si ≥ | Fe ≤ | Al ≤ | Ca ≤ | P ≤ |
|---|---|---|---|---|---|
| Content | 99.9999 | 0.15 | 0.15 | 0.01 | 30ppm |
Production Process
Process Master – Where Science Meets Craftsmanship!
Born from two revolutionary technologies
Modified Siemens Process: Like alchemy, I transform trichlorosilane into rod-shaped poly-Si-pure, scalable, and reliable.
Silicon Hydride Fluidized Bed Process: Like magic powder, I produce granular poly-Si with 70% lower energy costs-sustainable and future-proof.
Applications
Green Energy Pioneer – Lighting Up the World!
My mission? To revolutionize energy:
- Solar Empire: Powering 75%+ of global solar installations, turning rooftops and deserts into power plants.
- Semiconductor Hub: Enabling smarter chips, sensors, and AI devices.
- Future Frontiers: Flexible electronics, nanotechnology, and medical innovations-ready to blaze new trails!

Everything You Need to Know
Q: What is the minimum order quantity (MOQ) for Polycrystalline silicon?
A: MOQ is 25 ton for trial orders.
Q: How is polysilicon classified by purity?
A:Metallurgical Grade (5N-6N): Used in construction, automotive
Solar Grade (6N-9N): Dominates photovoltaic production (98%+ market share)
Electronic Grade (9N+): Required for semiconductor manufacturing
Q: What are the applications of N-type vs. P-type polysilicon?
A: N-type: Doped with phosphorus/arsenic, higher efficiency (e.g., TOPCon/HJT solar cells)
P-type: Doped with boron/aluminum, cost-effective but less efficient
Q: What packaging options are available?
A: We use double-layer waterproof woven bags (1000kg/bag) or vacuum-sealed bags for sensitive applications.
Q: How does Fengyang Metallurgy ensure product quality?
A: Adheres to national standards (GB/T 25074, GB/T 35307) for solar-grade and granular silicon 917.
• Employs the combination of Siemens method and silane method to meet the high efficiency technology requirements such as TOPCon/HJT
