Abstract
The fusion cast zircon-alumina refractories are used without competition from other refreactories in the lining of glass melting tanks. However, recent trend using similar compositions of bricks made by sint ring technique is widely spreading. This is due to the relatively lower costs besidsome advantages including their relatively high thermal shock resistivity. Also, these refractories are recommended for application in the steel industry as ladle bricks for high capacity ladles (>100 tons capa:city). Therefore, the present work was carried out in order to study the constitution and properties of some zircon-alumina refractories prepared by the semidry pressing and slip casting techniques presently available in the Egyptian refractories plants.
The study proceed along the investigational lines given below.
