Importance of Preheating Process:
Proper preheating is essential for ensuring the longevity of silicon carbide crucibles. Neglecting this step can lead to premature failure. Here’s a recommended preheating procedure:
- 0°C-200°C: Oil slow heating for 4 hours, electric slow heating for 1 hour.
- 200°C-300°C: Energize and heat slowly for 4 hours.
- 300°C-800°C: Slow heating for 4 hours.
- After Furnace Shutdown: Follow gradual reheating guidelines to maintain crucible integrity.
