چکیده انگلیسی
The compressibility of nitrogen doped zirconia (βⲠzirconium oxonitride, Zr7O11N2) has been measured at room temperature up to 10 GPa in hydrostatic pressure medium, using a diamond anvil cell and X-ray powder diffraction. A least squares fit of the third order Birch-Murnaghan equation of state to the experimental V(p)-data resulted in a bulk modulus of B0=254GPa and its first pressure derivative of B0â²=14(!). The obtained B0-value exceeds that of undoped monoclinic ZrO2 (212 GPa) and is comparable with that of the cubic (267 GPa) or the first orthorhombic high-pressure modification (oI, 243 GPa), which are discussed as potential hard materials. The exceptionally high value for B0â² arises as consequence of vacancy ordering and preferred compression.
