Compression of zeolites in penetrating fluids: an overview

open access: yes, 2017
Over the last two decades, a new light was shed on the high-pressure behavior of zeolites and on the most important mechanisms adopted by these materials to accommodate compression. However, the early discovery of the P-induced intrusion of H2O molecules
