The influence of Na~+ and Mg~(2+) exchangeable cations on surface properties of clay minerals

摘要

It is shown that Na and Mg modifications of kaolinite interact with water vapor more than 1.5 times less intensely than the untreated monomineral kaolinite because of the possible formation of metastable structures on the mineral grain surface.in thecase of montmorillonite saturated with NaCl and MgCl_2,the sructures formed on the mineral surface are unstable and get destroyed upon dialysis.
