Abstract

The equation of state of the recently discovered oxygen-bearing cubic zirconium (IV) nitride, c- Zr2.86 (N0.88 O0.12) 4, was measured at room temperature in a diamond anvil cell using x-ray powder diffraction combined with synchrotron radiation. From these studies the bulk modulus B0 =219 (13) GPa and its first pressure derivative B0′ =4.4 (1.0) [or B0 =223 (5) GPa, for B0′ fixed at 4] were obtained. Applying nanoindentation techniques the reduced modulus Er ≈220 GPa and hardness H≈18 GPa were measured for porous c- Zr2.86 (N0.88 O0.12) 4. The shear modulus of c- Zr2.86 (N0.88 O0.12) 4 was estimated to be at least G0 =96 (13) GPa using the experimental data of B0 and Er, exclusively.
