Abstract
Energy saving of 42-pair Siemens reactor for polysilicon production (ScienceDirect). Fetched by the auto-model research pass; the figures below are cited from this source in the model's flow, idiot-index, energetic-index, and market tabs.
Key facts
- Siemens process (electronic-grade polysilicon, 9N-11N) energy ~100-200 kWh/kg, optimized cases ~44-120 kWh/kg
- Convection heat loss ~23.6 kWh/kg, radiative loss ~20.5 kWh/kg in a 36-rod reactor
- Electronic-grade polysilicon purity <1 ppb impurities
Reviewer note
Real source gathered during the extend-silicon-stack research pass (2026-06-21). Figures attributed to it in the model link back here.
