Calcined Bauxite
1.High refractoriness
2.Chemical stability
3.High Hardness
4.Excellent Abrasion Resistance
Description of Calcined Bauxite:
Calcined bauxite is a refractory material made from natural bauxite ore (mainly Al₂O₃) after high-temperature calcination (usually 1200℃-1700℃). The core is to improve performance by removing crystal water, increasing the alumina content and mineral phase transformation (such as conversion to corundum phase) through calcination.
