Cerium is a fascinating f-electron metal with a complex phase diagram. Using the diamond anvil cell and synchrotron x-ray sources we have been able to study cerium to a pressure of 330 kilobars. Radial x-ray diffraction techniques have been used to ensure a more accurate pressure-volume curve at room temperature. Two different purities of cerium (99.9% and 99.99%) have been examined with noticeable differences. This work has produced high quality data that can be used to generate an accurate multi-phase EOS for cerium. The techniques developed in these experiments can further be utilized to obtain accurate EOS data for other materials of interest.
