Abstract

Clinoptiloite transforms to PHILLIPSITE under hydrothermal conditions in the presence of alkaline fluids. The effect of Na+ and K+ concentrations, temperature and time are the variable parameters in the present study. ALKALINE SOLUTIONS of KOH and NaCl were used in concentrations of 1.25 up to 7.5mol/lit at temperatures of 100 and 150oC. Results of this study show that PHILLIPSITE has been synthesized at 100 and 150oC and high concentration of K+ at the expense of clinoptilolite dissolution. With increasing K+ content of the fluids and reaction time, the amount of PHILLIPSITE increases drastically. Powder X-ray diffraction study has revealed a monoclinic (pseudo-orthorhombic) symmetry with the unit-cell parameters as follows for PHILLIPSITE: a: 10.104 A, b: 14.305 A, c: 14.618 A , b: 91.401o.
