The phase relation ofwas investigated up to a pressure of about 67 GPa by synchrotron x-ray diffraction and analytical transmission electron microscopy. We found thatperovskite decomposes intowüstite and orthorhombicphases (ideally) at conditions above 42 GPa and 2000 K. Our study also demonstrates that the phase assemblage ofandis the densest of the various systems reported so far for.
