TL;DR: In this article, the influence of the nature and chemical composition of the starting material, pH and concentration of the mineralizing agent (NaOH) and reaction temperatures and time on the zeolitization process is discussed and compared to the performance of Lipari pumice.

TL;DR: In this paper, perlite from Sardinia (Italy), Milos (Greece) and Siberia (USSR) have been evaluated in terms of chemical composition, phase analysis, iron distribution, morphology and thermal properties for application as raw material in zeolite synthesis.

TL;DR: In this paper, the Si Al ratio of the starting material was of special importance in that zeolites formed with Si Al ratios similar to or smaller than that of the parent material.

TL;DR: In this paper, the influence of the nature and chemical composition of the starting material on the zeolitization process is discussed, and the dissolution rate of the alumino-silicate is strongly influenced by the size distribution of different granulometric fraction of the three perlite samples.

TL;DR: The influence of reaction temperature, alkalinity and chemical composition of gel on the formation of zeolite A was investigated in this paper, where the reaction temperature influences both the nucleation (reaction time) and the crystallinity (crystal growth).
