Effect of Dry Grinding of Pyrophyllite on the Hydrothermal Synthesis .

Zeolite Na-X and Na-A were synthesized by mechanochemical activation of pyrophyllite and pyrophyllite-gibbsite mixture followed by hydrothermal reaction in NaOH solution at 75°C under atmospheric pressure. The formation of zeolite Na-X and Na-A was depended on the degree of activation caused by grinding; i.e.,.
