Abstract
Several glasses were prepared by melting different compositions containing Sarcheshmeh copper slag, calcium carbonate, and silica. Glassceramics were obtained by heat treatment of these glasses at their DTA peak temperatures. Mechanical properties, microstructure, thermal expansion coefficient and acid resistance of glasses and glass-ceramics were determined. Substitution of Fe2O3 by CaO was found to decrease the acid resistance of glasses while their mechanical strength increases. The acid resistance of the optimum glass was higher than its glassceramic.
