de Cavis offers fiber-free refractory bricks for smaller ovens and laboratory equipment for application temperatures up to 1700°C, either as semi-standard stones or, on request, in special formats.

Thanks to their uniquely homogeneous microstructure, our refractory bricks are also of outstanding quality with their low thermal conductivity, high strength and good machinability. They can be shaped by means of sawing, drilling, turning or milling. In addition to isotropic structures, for example, we can also produce layer structures with different porosities, thereby giving the material unique combinations of properties. By combining a highly porous material with a dense surface layer, the resulting component not only has excellent thermal insulation but also good abrasion and erosion resistance.
