Overview
Product Overview
KORVANTO CHAM™ is a premium-grade calcined refractory clay (Chamotte) produced from carefully selected kaolinitic clays and fired at high temperatures to develop exceptional thermal stability strength and dimensional consistency. The calcination process transforms the clay into a highly stable refractory aggregate capable of withstanding extreme temperatures and thermal cycling.
Processed through advanced crushing screening and grading systems KORVANTO CHAM™ is available in various particle sizes and alumina grades to meet the requirements of refractory manufacturers ceramic producers foundries steel plants cement kilns and other high-temperature industries.
Its superior resistance to thermal shock abrasion shrinkage and chemical degradation makes it an ideal raw material for fire bricks castables refractory mortars kiln furniture insulation materials and technical ceramics.
