The solid state reactions of dickite and pyrophyllite with CaO at 900℃ were investigated paying attention to the direction of diffusion, the preference of reactivity of the two minerals, and to the difference in the reactivity between edge and basal crystal surf aces . Pt-marker method was used for examining the direction of diffusion. The amount of CaO reacted was determined by glycerin-ethanol method. The conclusions obtained are as follows. 1. CaO preferentially diffuses into the clay minerals. 2. Pyrophyllite is more reactive with CaO than dickite. 3. Edge surfaces of dickite is much more reactive than basal surfaces. 4. Pyrophyllite shows no noticeable difference in the reactivity with CaO between the two crystal surfaces as of dickite.
