Key Advantages
- Resisting High Temperature: Withstands extreme temperatures up to 1750°C or higher, maintaining structural integrity in furnaces, kilns, and incinerators.
- Great Bulk Density: Dense structure (2.5-3.0 g/cm³) enhances mechanical strength, load-bearing capacity, and thermal conductivity.
- Low Iron Content: Minimal iron oxide impurities (<2%) prevent unwanted reactions and discoloration at high temperatures.
- Good Eroding Resistance: Excellent resistance to chemical erosion and slag corrosion in acidic or alkaline environments.
Applications
- Steel furnaces
- Iron making furnaces
- Glass kiln
- Ceramic tunnel kiln
- Cement kiln
