Zusammenfassung:The fire-clay is used for preparation of goods, in particular, of fire-resistant glasses. It has a high thermal resistance and strength, while their production allows the utilization of the waste refractory. The fire-clay device contains in %: a highallumooxide waste refractory from 60 to 80, kaolin from 10 to 20 and fire-resistant clay from 10 to 20. The high allumooxide refractory may partially be replaced with refractory class A to 50%, while their grain-metric composition is the following: grain size is between 0.5 mm - 50% and from 1 to 2 mm - 50%.
