Chamotte & Calcined Clay
Calcination removes moisture and organic matter to create stable, inert ceramic raw materials.
1600°C+
Calcined Bauxite
Rotary-kiln processing develops density, mechanical strength and high-alumina durability.
2000°C+
Brown Fused Alumina
Electric arc fusion creates a hard crystalline structure for abrasives and advanced refractories.
Thermal transformation
Temperature defines performance
Each mineral family is processed through a distinct thermal route, creating a different balance of stability, density, hardness and conductivity.
Stability
Chamotte supports thermal shock resistance and controlled insulation.
Density
Calcined bauxite delivers mechanical strength in harsh lining environments.
Hardness
BFA supports grinding, cutting and high-wear refractory applications.
