Abstract
A high pressure and high temperature in‐situ X‐ray diffraction experiment of MgSiO3 perovskite was conducted using a sintered diamond multianvil apparatus (SDMA8) combined with the synchrotron radiation. The unit cell parameters of the perovskite were measured up to 1095°C at about 20.5 GPa. The thermal expansion coefficient is 0.8(±0.8)×10−5 K−1 at 20.5 GPa and room temperature.
