To obtain kaolinite at low temperature and pressure from the system Si(OH)4-Al3+-H2O, the sixfold coordination of aluminum is a necessary prerequisite. Kaolinite was synthesized at pH values from 2 to 9 and with a ratio of SiO2 to Al2O3 in solution from 1 to 10 by means of the complexation of Al3+ and fulvic acid.
