Kaolinite and Kaolin Si2Al2O5 OH

Kaolinite is a clay mineral, kaolin is clay, but these terms are often used as synonyms. The results obtained for kaolin and for kaolinite are presented together. Kaolinites converted into specilic form (Na-, Ca-) are also included. Collections of PZC and/or charging curves of kaolinite from different sources can be found in [2246-2248], 

Described as acid-washed and/or as received in a series of papers presenting similar results.
