In order to improve the dispersibility of zeolite powders prepd. from a kaolinite-contg. reaction mixt. by aging with subsequent hydrothermal crystn. and sepn. and drying of the powder, the kaolinite used in the reaction mixt. is 1st subjected to mechanochem. activation in air or N2 until the total intensity of diffraction lines for the kaolinite is reduced to 40-95% of the intensity initially seen, and then treated in H2SO4, alkali solns., or water (solids:liq. ratio 1:4.3-10) until the total diffraction line intensity is reduced to 50-100% of the initial intensity.
