Abstract

Glass-ceramics are produced by crystallization of glass. It is also produced using waste materials, and particularly silicate based wastes such as: coal ash, slag, fly-ash and waste from incinerators. The production of glass-ceramics from these wastes using different methods is considered in this paper. The properties of the product are also considered; this review focused on silicate wastes into useful production of glass ceramics products. Previously, a review using general wastes applicable in glass-ceramics production has been reported. In addition to oxide composition in the waste materials, the effect of adding other oxides such as titanium oxide on the mechanical and physical properties of the product in relation to the desired property needed for various forms of applications. Avoiding incineration of the waste material for the reduction of environmental pollution, as a result of immobilization of the toxic waste in the matrix of the glass-ceramic are also considered in this review.

Key words: Effect, silicate-based waste, properties enhancement, glass-ceramics.
