A-18 EFFECTS OF CLEAR AND AMBER CULLET ON PHYSICAL AND MECHANICAL PROPERTIES OF GLASS-CERAMICS CONTAINING ZINC HYDROMETALLURGY WASTE(Session: Glass)

Abstract

Glass-ceramics were prepared by using hydrometallurgical zinc waste and waste glasses (clear and amber cullet) as raw materials. The mixtures were melted at 1450℃ for 1 hour. The proportion of Zn-waste in the mixtures varied from 20 to 60 wt%. The obtained glasses were ground and pressed into a bar shape and then sintered at 750℃ and 850℃ for 2 hours. Their physical and mechanical properties were determined. It was found that the density of the glass-ceramics increased with an increase in the proportions of Zn-waste.
