From the following equation (as given by Gastuche and DeKimpe, 1962) for kaolinite formation 2 Al(OH)3 + 2 H4SiO4 → Si2O5.2 Al(OH)3 + 5 H2O it can be seen, that five molecules of water must be removed from the reaction for every molecule of kaolinite formed.
A partir da seguinte ecuación (como indicaron Gastuche e DeKimpe, 1962) para a formación da caolinita 2 Al(OH)3 + 2 H4SiO4 → Si2O5·2 Al(OH)3 + 5 H2O pode verse que deben ser retiradas da reacción cinco moléculas de auga por cada molécula de caolinita formada.
