Structural and morphological alterations during zeolite crystallization process

Stages of zeolite A crystallization have been investigated by PALS, and compared to the results obtained by XRD, FTIR and SEM. Attention was paid on initial amorphous zeolite precursors as prepared and at the beginning of the crystallization process in order to elucidate structural changes occurring inside amorphous matrix. Evolution of order provides more space for positronium formation as well and PALS has proved itself as a useful method for monitoring the process.
