INVESTIGATION OF DISSOLUTION OF ALUMINOSILICATES IN AQUEOUS ALKALINE SOLUTION UNDER LABORATORY CONDITIONS

T. Hanzlíček, M. Steinerová-Vondráková

The investigation was aimed to the elucidation of the properties of colloidal mixtures of aluminosilicates in an aqueous alkaline solution and to the verification of the possibilities of sol-gel reactions at room temperature and atmospheric pressure. Basic factors influencing the reaction course are the dehydroxylation of the starting materials, their particle size distribution, the pH of alkaline aqueous solution and the intensity of agitation.
