Pressure-induced phase transitions and volume changes in Hf02 up to Gpa
Leger, Jean Michel; Atouf, A.; Tomaszewski, P.E.; Pereira, Altair Soria (1993) [Artigo de periódico]The phase transformations and pressure-volume dependence of Hf02 have been investigated at room temperature by angle-dispersive powder x-ray diffraction under high pressure to 50 GPa in a diamond anvil cell. The phase ... -
Pressure-induced structural phase transitions in zirconia under high pressure
Leger, Jean Michel; Tomaszewski, P.E.; Atouf, A.; Pereira, Altair Soria (1993) [Artigo de periódico]Angular-dispersive x-ray in situ powder-diffraction experiments have been performed on pure zirconia, Zr02, at room temperature under high pressure up to 50 GPa. Under increasing pressure four phases were successively ...
