A high-pressure Raman study of BaCeO 3 was performed at room temperature. This perovskite compound undergoes two phase transitions at about 22 and 28 GPa. The increase in the number of bands is an indication that the symmetry is lowered and that the compound does not evolve towards the ideal cubic p

A high-pressure single-crystal x-ray diffraction study of perovskite-type MgSiO 3 has been completed to 12.6 GPa. The compressibility of MgSiO 3 perovskite is anisotropic with b approximately 23% less compressible than a or c which have similar compressibilities. The observed unit cell compression g
