摘要

This research explores the feasibility of utilizing secondary raw materials for the production of glass and glass–ceramic materials, contributing to sustainable waste management and resource efficiency. Fly ash from thermal power plants, glass container cullet, and sugar beet factory lime (SBFL) were repurposed as alternative raw materials that would otherwise be disposed of in landfills. By incorporating these waste-derived materials, the study aims to develop environmentally friendly glassy products while reducing the reliance on conventional raw materials. The subsequent sinter-crystallization of these glasses enabled the formation of dense glass–ceramic materials with apparent porosity below 1%, ensuring good mechanical properties. A comprehensive evaluation of the physical, mechanical, and chemical properties was conducted to assess the suitability of the produced materials for various applications. X-ray diffraction analysis identified the primary crystalline phases formed during sinter-crystallization, including anorthite, wollastonite, and gehlenite. The Vickers hardness of the samples is comparable to other waste-derived glass–ceramics. The chemical durability tests demonstrated excellent resistance to degradation in neutral, acidic, and alkaline environments. Overall, the findings highlight the potential of utilizing industrial waste to produce high-quality glass and glass–ceramic materials with desirable properties and minimal environmental impact.
