Clinoptiloite transforms to phillipsite under hydrothermal conditions in presence of alkaline fluids. The
effect of Na+ and K+ concentrations, temperature and run duration are being considered as the variable
parameters in the present study. Alkaline solutions were used in concentration of 1.25 up to 7.5 mol/lit under
temperatures of 100 and 150 °C. Results of this study show for the first time that phillipsite is synthesized at
100 and 150 ºC and high concentration of K+ Cations. Powder X-ray diffraction study has revealed a
monoclinic (pseudo-orthorhombic) symmetry with the unit-cell parameter of: a: 10.104 Å, b: 14.305 Å, c:
14.618 Å, β: 91.401º for phillipsite.
