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
