Extract

It is surprising how reluctant many clay mineralogists have been to attribute the small cation exchange capacity of kaolinite to a correspondingly small isomorphous replacement. After all, only one silicon in 400 need be replaced by aluminium to give an exchange capacity of 2 m.e./100 gm., and it is very difficult to prove or disprove so small a replacement by chemical analysis.
