In addition to the programme for quartz raw materials we also produce wet and dry acid refractory masses, made of our raw materials, which are used to wall-in the cupola and industry furnaces for cast gray iron and nodular cast iron, and to wall in the casting pots and pans in foundries and ironworks.

As addition to the wet and dry acid refractory masses we also produce a range of special refractory masses. Above all we are proud on our EKA Focor LPN product which is used in foundries for surfacing the casting pans and it has the extraordinary properties which can ensure high savings in the foundry’s time and energy. We also market castables and the various special refractory materials, which are produced by our strategic partner, EKW GmbH, and certain equipment for the building-in of refractory materials.
