Pressure-induced structural phase transitions in zirconia under high pressure
(1993) [Journal article]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 ... -

Variation of the refractive index and polarizability of sapphire under high pressures
(1993) [Journal article]In this article we present the experimental results for the pressure variation of the refractive index of sapphire up to 16 GPa, obtained with an interferometric method, using the diamond anvil cell. In the range of ...
