Vitrification of lignite fly ash and metal slags for the production of glass and glass ceramics

^aLaboratory of Inorganic and Analytical Chemistry, Chemical Engineering Department, National Technical University of Athens, 9 Heroon Polytechniou Str., 157 73 Athens, Greece

Abstract

This work focuses on the production of glass and glass-ceramics by using industrial wastes or by-products, e.g., two fly ashes from the combustion of lignite, a slag from the production of Fe-Ni and a slag from the making of steel. Vitrification took place at 1 350°–1 450°C and crystallization was achieved by heat treatment at 900, 950 and 1 000°C. The capability of the waste to be vitrified and subsequently devitrified was determined by XRD techniques. The crystalline phase depends greatly on the structure of the by-product and the heat treatment. The final products showed low leachability and good hardness (5.5 - 6 on the Mohs hardness scale.....the norm for most glass)
