Strategies to improve the yield and quality of silicon metal
- Raw material optimization: Select higher purity micro-silicon powder as raw material to reduce the impact of impurities.
- Reaction temperature control: The reaction temperature is controlled in the range of 1500-2000°C to ensure a complete and efficient reaction.
- Reducing agent selection: Select a reducing agent with low ash, low sulfur and low phosphorus (such as petroleum coke, pulverized coal, etc.) to improve the quality of metal silicon.
- Furnace body design: reasonable design of the reactor, optimize the atmosphere flow, improve the thermal efficiency and reaction efficiency.
