Abstract
Particulate synthetic zeolite is micronized in a liquid organic medium to form a micronized zeolite product having an average (mean) particle size of about 2 microns or less and containing at least 90% by weight, based on the dry weight of the zeolite product, if isolated, of particles no larger than about 5 microns. Preferably, the micronized zeolite product has a mean particle size of 1 micron or less, and at least 90% by weight of the zeolite product, based on the dry weight of the zeolite product, if isolated, has a particle size of 2 microns or less. The liquid organic medium used is (a) inert or substantially inert, (b) devoid or substantially devoid of water, and (c) devoid of a dispersant.
