Features and Properties
- High-temperature Resistance: The refractoriness is > 1790℃, and the long-term service temperature reaches 1700℃.
- Chemical Stability: By optimizing the Al₂O₃ content and impurity control, the erosion resistance is significantly improved.
- Thermal Performance: Low thermal conductivity, and the thermal shock stability can pass more than 200 rapid heating and cooling tests.
- Mechanical Strength: High compressive strength supports the structural stability of the kiln.
