Cellular Glass-Ceramic from Recycled Residual Glass, Metakaolin and Coal Fly Ash

Year: 2024

Type: article

Abstract: In this paper, the care for environmental health was promoted, selecting raw materials that meet these requirements. Thus, recycled glass waste in predominant proportion, coal fly ash as a by-product of the energy industry, and a natural alumina-silicate material (metakaolin) were used. Silicon carbide (SiC) was chosen as an expanding agent. Although insignificantly used until now for high-temperature industrial processes, the microwave heating has been adopted to perform the sintering and expanding process. The results showed very good thermal insulation properties and high mechanical strength of the optimal expanded product.
