Crucible for High Frequency Induction Furnace
“White Phoenix”
- This product can reduce the contamination of B, P, Fe and etc. in the molten silicon.
- Because of its CIP production, it exhibits much higher uniformity and compactness compared with cast method or press method.
- Molten Silicon has higher penetration characteristics. However, It protects such penetration that it
reduces the risk of penetrated substance to cause structural spalling. It has also higher thermal spalling resistance which prevents cracking.
Various shapes are available up to 1100mm diameter and 1600m height.
