Our andalusite or mullite based high alumina content refractory materials are prepared from raw materials selected with the utmost care.

Whether andalusites, sintered or fused-cast mullites, these raw materials meet the technical specifications drawn up by our laboratory and are submitted to regular inspections.

Our andalusite based grades exhibit outstanding resistance under load at high temperature, small and regular expansion, and excellent thermal shock resistance

Our mullite based grades exhibit outstanding resistance under load at high temperature and good chemical corrosion resistance.
