Synthesis and Properties of Sr <sub>9</sub> Ce <sub>2</sub> W <sub>4</sub> O <sub>24</sub> Quaternary Perovskite
We report details on the synthesis and properties of strontium cerium tungstate, Sr<sub>9</sub>Ce<sub>2</sub>W<sub>4</sub>O<sub>24</sub>, a quaternary perovskite that has not yet been synthesized in pure form. Room-temperature powder X-ray diffraction (XRD) identified the most probable space group as tetragonal <i>I</i>4<sub>1</sub>/<i>a</i>. X-ray photoelectron spectroscopy confirmed that the material obtained after synthesis contained cerium in both 3+ and 4+ charge states, as well as tungsten in 5+ and 6+ states. Temperature-dependent Raman and XRD measurements done at 1 atm air and N<sub>2</sub> excluded the possibility of a phase transition occurring within the 8-873 K; however, when exposed to air, the compound decomposes to a mixture of various salts and oxides just above 573 K. When compressed at room temperature, a possible transition toward lower-symmetry, monoclinic (<i>C</i>2/<i>c</i> or <i>C</i>2/<i>m</i>) space groups was detected between 12.5 and 15 GPa.
