Powder diffraction analysis of cerium dioxide at high pressure

  • L. Gerward (a1) and J. Staun Olsen (a2)
Abstract

CeO2 transforms to an orthorhombic PbCl2-type structure at a pressure of about 31 GPa. The phase transition is accompanied by a 9.8% volume contraction. The bulk modulus of the low-pressure fluorite-type structure is 236(4) GPa. Comparisons are made with the high-pressure behaviour of UO2 and ThO2.
