Lipari pumice has selectively been transformed into zeolites in NaOH/NaCI media. The influence of NaCI and retention times on the degree of zeolitization is discussed for different NaOH concentrations. In the absence of NaCI, the high SIO2/AI203 ratio zeolites ZK-19 and phillipsite appear after long
