The effect of pressure and temperature on the stability of all-silicon ZSM-5 zeolite is re-ported for the first time.It has been found that ZSM-5 zeolite is directly transformed into ZSM-11 zeolite un-der the pressure of 4.0 GPa at room temperature and that this transformation is irreversible.ZSM-5 zeoliteis transformed into β-quartz by high pressure quenching,which is obtained for the first time at room temper-ature,and coesite under high pressure and high temperature.
