ZACCARON, Alexandre et al. Analysis of clay ceramic microstructure with the glass waste incorporation. Rev. cienc. tecnol. [online]. 2022, n.37, pp.21-30. ISSN 1851-7587.  http://dx.doi.org/10.36995/j.recyt.2022.37.003.

The study examined the microstructure of ceramics with the addition of glass waste at different temperatures ranging from 800 to 1000 °C. Samples were molded by piston without vacuum, with the incorporation of 20% (weight) of glass bottles, with coarse particles, for a better identification. The raw materials were analyzed chemically and mineralogically by XRF and XRD. The microstructural characterization was carried out by scanning electron microscopy, SEM and optical microscopy, in order to analyze the behavior of grain boundary and the interaction between the materials. The results showed that there is compatibility between the materials, where the increase in temperature causes a greater interaction, but when this temperature exceeds 900 ° C, pores appear in the glass, a phenomenon known as overfiring.
