Influence of OH- concentration on the illitization of kaolinite at high pressure [PDF]
, 2011 The products of hydrothermal reactions of kaolinite at 300°C and 1000 bars were studied in KOH solutions covering an OH- concentration, [OH-], of 1M to 3.5M. XRD patterns indicated a notable influence of the [OH-] on the reaction.
