摘　　要：Calcium hexaluminate is one from such perspective materials. 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 metals. 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.Calcium hexaluminate is one from such perspective materials.
