Abstract

A double-stage multianvil system was developed to conduct in situ X ray diffraction study at high pressures. The system has been used in conjunction with intense synchrotron radiation to study the phase transitions of MgSiO₃ and the thermal expansion of MgSiO₃ perovskite. At pressures between 20 and 30 GPa, a series of phase transitions from spinel+stishovite through ilmenite to perovskite were observed. The results provide the phase stability relation of MgSiO₃ and the thermal equation of state of MgSiO₃ perovskite at pressures corresponding to the boundary between the upper and lower mantle. -from Authors
