Abstract: Currently there is ambiguity about the space group of the first high pressure phase of ZrO 2 . Early Raman spectroscopic measurements on a single crystal in a diamond anvil cell pointed to a structural transformation at 3.5 GPa, and later in-situ X-ray diffraction studies concluded that this structure is orthorhombic with space group Pbcm. From a subsequent analysis of neutron diffraction patterns of ortho-I phase quenched from 6 GPa and 600 °C it was concluded that the space group of this phase is Pbca and not Pbcm. We have re-investigated this using Raman spectroscopy and factor group analysis, and show that the space group indeed is Pbcm and not Pbca.
