Imerys Refractory Minerals is the world’s leading producer of calcined products for the refractory industry.
Our Mulcoa® range of materials is recognized as the global benchmark. Clays are mined from the South Georgia kaolin belt in the US, and blended to obtain chemistries between 45 and 70% alumina.
The transformation of clay into mullite generates a structure that gives the product the required characteristics for refractory applications:
Good creep resistance
Low thermal conductivity
Excellent thermal stability
Good thermal shock resistance
Resistance to most chemical attacks
Mulcoa® is a mainstay of refractory production, wherever volume stability, resistance to carbon monoxide attack and all-around performance are required.
