Crystalline zeolite A was amorphized by mechanical and thermal treatments, and the resulting changes in the atomic arrangement are characterized by HEXRD, Al-27 MAS NMR and Raman spectroscopy. HEXRD measurements revealed that the 6R and 8R rings are distorted and/or destroyed, while the 4R ring is preserved during mechanical treatment, but all rings are distorted and/or destroyed by thermal treatment. Data from Al-27 MAS NMR and Raman spectroscopy also support these results. Furthermore, recrystallization behavior is found to be different between mechanically and thermally amorphized solids.
