Mineralogical dataset of natural zeolites from Lessini Mounts, Northern Italy: Analcime, natrolite, phillipsite and harmotome chemical composition

Revealing the evolution of local structures in the formation process of alkaline earth metal cation-containing zeolites from glasses

“…2(d)), similar to the natural harmotome mineral. 31 These observations are consistent with the previous reports that the rapid dissolution of the glass occurs in the alkaline solution with a suitable pH, and the condensation of the aluminosilicate species in the solution leads to the formation and precipitation of zeolites. 9,32 During such a dissolution-reprecipitation process in the pH 13 NaOH solution, the release of the Ba 2+ cations into the liquid phase is negligible, and the chemical compositions of the products synthesized for different periods are similar according to the results of ICP-AES (Table 1).…”
