Preparation and Properties of High Iron Oxide Content Glasses Obtained from Industrial Wastes

Abstract

The formulation and preparation of new glasses has been carried out by the recycling ofgoethite (FeOOH) industrial wastes originating from zinc hydrometallurgy with glass cullet and dolomite as complementary raw materials. The mineralogic (XRD) and microstructural (SEM, TEM) characterization of the product has been determined and the thermal, mechanical and chemical properties of original glasses have been measured. The results indicate that glass production is an effective recycling method for this kind of waste, yielding black stable glasses with good mechanical and chemical properties. © 1997 Elsevier Science Limited.
