ABSTRACT:
There is disclosed a method of producing a slurry composed of ion-exchanged, synthetic mica crystals dispersed in a polar liquid. The method comprises providing a synthetic, lithium and/or sodium, water-swelling body of selected crystal type, and dispersing the mica body in the polar liquid while simultaneously effecting an exchange of larger cations from a contacting source with lithium and/or sodium ions from the mica crystals. The synthetic mica body may be vigorously mixed in a dilute solution of the exchangeable ion source. Alternatively, the mica body may be disintegrated in a mixer, the exchangeable ion source added to form a paste and more liquid added to dilute the paste.
