RCPL offers various intricate shapes and parts of thermal engineering. The refractory material offered by RCPL is porous alumina and porous cordierite which offers a range of thermal expansion, mechanical strength and porosity criteria.

Both of the material has a very low linear expansion, low coefficient of thermal expansion and excellent resistance to thermal shock.

The applications include ceramics parts for heat treatment furnaces, investment casting, electrical induction, heating element assemblies, annealing carburizing etc.
