    Quartz products made by slip casting

    From finely milled fused quartz it is possible to obtain, by the slip method, adequately strong quartz products with high thermal-shock resistance at low firing temperatures. A substantial increase in the stre...

    Investigation of the drying process in fine-grain alumina articles

    Unfired alumina after acid processing contains up to 3% hydrates and oxychlorides of aluminum. In the materials fired at high temperatures the hydrates and oxychlorides of aluminum are practically absent (0.1%...

    Effect of preliminary heat treatment of alumina on the thermal-shock resistance and strength of corundum ceramics

    The firing temperature of the starting alumina is one of the important factors influencing the formation of the microstructure of corundum materials and determines the properties of the ceramics. At low alumin...

    Influence of the technological factors on the quality of quartz steelcasting nozzles

    To produce quartz nozzles of uniform vertical and transverse density by slip-casting the slip must be of optimal density (1.73−1.76 g/cm3) and the stabilization period of optimal length (at least 30 h).
