This is a comparative study on the high‐pressure behavior of microporous materials with an MFI framework type ( i.e. natural mutinaite, ZSM‐5 and the all‐silica phase silicalite‐1), based on in‐situ experiments in which penetrating and non‐penetrating pressure‐transmitting media were used. Different pressure‐induced phenomena and deformation mechanisms ( e.g. pressure‐induced over‐hydration, pressure‐induced amorphization) are discussed. The influence of framework and extra‐framework composition and of the presence of silanol defects on the response to the high pressure of MFI‐type zeolites is discussed.
