Lightweight refractory bricks

Lightweight refractory bricks are used as thermal insulation on furnaces and other thermal plants.

These insulation products are characterised by a combination of mechanical toughness and low thermal conductivity. Lightweight refractory bricks based on hollow sphere corundum are intended for lining high-temperature kilns used in the ceramic industry. Their excellent thermal shock resistance and low heat storage capacity makes these products particularly suitable for periodically operated kilns.
