There have been increasing efforts to utilize energy by-products （EBp） all over the world. In the czech Re- public fly ash is usually used in ceramic technology, es- pecially in brick manufacturing and for ceramic tiles. The average production of EBp is about Ig million tons per year. The range of potential products, where EBp could be used, is very wide and energy by-products have become an important raw material source. In this paper the attention was focused on cla.s.C fly ash and its usage in field of refractory materia.s. Experimental works were carried out on mixtures with fly ash and clay. There were a.s. tested batches for lightweight fireclay bricks. The maximal amount of CFa.s.ould be up to 50%.

Calcium hexaluminate is one from such perspective materia.s. It is characterized by high refractoriness （ above 1 830 ~C ） , as well as properties stability in reducing atmosphere, high alkali- and slag-resistance, low thermal conductivity and wettability by molten meta.s. In this work influence researches of fused calcium hexaluminate material additive in amount of 5%, 15% amt 25% on the main properties of alumina refractories were carried out. It is established that, the refractories containing the additive of 25% calcium hexaluminate material are characterized by the highest properties, slightly impregnated with metal melt and the highest metal corrosion resistance. The alumina purging plugs fi）r blowing of metal with calcium hexaluminate material additive are produced and intended to one metallurgical plant of Ukraine for carrying out tests.
