SYNTHESIS, CHARACTERIZATION OF ANALCIME AND ITS APPLICATION IN WATER TREATMENT FROM HEAVY METAL توليف ، توصيف الأنالسيم وتطبيقه في معالجة المياه من المعادن الثقيلة [PDF]
Assiut University Bulletin for Environmental Researches, 2018 In this study analcime was successively synthesized from kaolinite as a raw material using the fusion with NaOH method. The conditions of hydrothermal crystallization (zeolitization) were found to be at temperature of 170C˚, and time span between 36 h ...

Dehydration dynamics of analcime by in-situ synchrotron powder diffraction
, 1999 The continuous structural transformation of tetragonal analcime (Na15.87Al15.20Si32.64 O-96. 16.3H(2)O) upon dehydration was studied, using Rietveld structure analysis of temperature-resolved powder diffraction data collected using synchrotron radiation.
