Abstract

Effect of waste Cr/Al 2 O 3 catalyst addition to fusible charge and firing temperature on the basic properties of the fired ceramics is studied. The dependence of strength, density and water absorption on firing temperature on 960, 1060 and 1160°C is established. It is proven that increasing firing temperature up to 1160°C provides less leachability of Cr(VI) from samples and increased environmental safety of ceramics.
