Sažetak

Preparation of amorphous aluminosilicates precursors with defined properties is a very important factor for further studies of nucleation and crystal growth of zeolites during their thermal and hydrothermal transformation into zeolites and special ceramics. This study presents the effect of an intensive mechanical force (ball-milling) on the properties of zeolite A and zeolite A with partially exchanged sodium ions with other cations (Li+, K+, Cs+, NH4+). The influence is studied of different cations on the mechanical and thermal stability of the zeolite framework and the formation of amorphous phases, as well as their transformation into nonzeolitic crystal phases after thermal treatment.
