K-smectite

Response of K-Smectites to WD Cycles in Water at 60°C. Results of these WD experiments are given in Table IV sample XRD patterns are given in Figures 3 and 4. The following patterns of reaction are evident from Table IV ... 

Figure 3. XRD patterns (CuK radiation ethylene glycol-solvated samples) for Sr-exchanged K-smectites that have been subjected to 100 WD cycles in water at 60°C. A low-angle shoulder that indicates a trace of R1 ordering is marked by a tick on the Black Jack pattern. Peaks labeled in nm.

Figure 5. Percentage illite layers versus layer charge for K-smectites subjected to 100 WD cycles in water at 60°C and 1 Sr-exchange. Numbers in parentheses refer to percentage of octahedral charge. Best fit line is for montmorillonites having 69% or more octahedral charge. Data from Tables III and IV.
