Slow amorphization of zeolites
- 19 Downloads
The dynamics of amorphization in two zeolites with different densities is investigated using high-pressure Raman spectroscopy. Slow amorphization of the denser zeolite under pressure leads to the formation of a low-density amorphous (LDA) phase that transforms into a more disordered high-density amorphous (HDA) phase with a further increase in the pressure. It is revealed that the LDA-HDA transformation is a first order phase transition occurring with an increase in the silicon coordination.
