The influence of reaction temperature on the hydrothermal conversion of rhyolitic Lipari pumice to zeolites in 2–5 NaOH has been investigated in the 65°–150°C range. Phillipsite, Zeolite pc, Hydroxysodalite, Faujasite, Analcime and a sodium aluminum silicate hydrate are formed as components of the product mixture. After 5 h at 130°C Analcime is obtained as a pure and highly crystalline compound.

Abstract
The influence of reaction temperature on the hydrothermal conversion of rhyolitic Lipari pumice to zeolites in 2–5 NaOH has been investigated in the 65°–150°C range. Phillipsite, Zeolite pc, Hydroxysodalite, Faujasite, Analcime and a sodium aluminum silicate hydrate are formed as components of the product mixture. After 5 h at 130°C Analcime is obtained as a pure and highly crystalline compound.File in questo prodotto:
