Abstract

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