Amorphous-to-amorphous phase transition in zeolites

摘要

A transition between two amorphous phases with different densities has been detected in zeolites at high pressures using Raman scattering. The Raman spectra measured at amorphous-to-amorphous phase transitions in zeolites and silicon are almost identical; this fact suggests a common nature of these transitions in both singleand multicomponent materials.
