Nucleation and crystal growth temperatures of glass were studied. The temperatures of maximum nucleation rate of the parent glass are 612 °C and 660 °C and crystal growth is at 776 °C and 1047 °C. At 776 °C a glass-ceramic of nepheline, wollastonite and akermanite is formed. In glasses treated at higher temperature nepheline becomes unstable and at 1047 °C a wollastonite-akermanite glass ceramic was obtained. The leaching tests show that the potentially toxic elements are effectively bound in the structure of the glass-ceramic, which can be considered inert.4 p.application/pdfengcc-by-nc-nd (c) The Author(s), 2022https://creativecommons.org/licenses/by-nc-nd/4.0/MineralogiaVidreVitroceràmicaJaciments mineralsMineralogyGlassGlass-ceramicsMineral depositsinfo:eu-repo/semantics/article7190932022-12-19info:eu-repo/semantics/openAccess
