Despite the fact that fly ash is mostly used in the construction industry in South Africa, a considerable amount of it is nevertheless dumped. Fly ash devitrification for the production of glass-ceramic composites has steadily become one of the applications being investigated internationally. The exploration of creating glass-ceramic composites from fly ash, various amounts of beverage waste glass, and magnesium oxide as key raw materials is reported in this paper. Fly ash was melted to make glasses. An arc furnace … Continue reading “Preparation and Characterization of Glass-ceramic Composites from South African Coal Fly Ash: A Recent Study”

Research on Effect of Li2O on the Properties of Bismuth Borate Glasses

Melt quenching is used to make borate glasses with Li2O and a set concentration of the heavy metal oxide Bi2O3. The impact of Li2O on borobismuthate glasses has been investigated. Glass density increases somewhat as Li2O content increases, although molar volume and glass transition temperature decrease. Infrared spectroscopy was utilised to investigate the structural properties of these glasses in the 400 to 4000 cm1 range. Bi3+cations are included in the glass structure as (BiO6) octahedral units, while boron ions are … Continue reading “Research on Effect of Li2O on the Properties of Bismuth Borate Glasses”
