Shock Compression of NiO to 130 GPa
Shock compression experiments on single crystal NiO grown by the Verneuil method have been carried out up to 132GPa using both propellant and two-stage light-gas guns. The shock states, recorded with the inclined mirror method, were analyzed by the free-suncce approximation and impedance-match solution. No discontinuous volume decrease was observed along the Hugoniot, indicating that NiO remains with the rocksalt structure to 132GPa. The isothermal compression curve, reduced from the Hugoniot, yields a bulk modulus of K = 184±5GPa assuming K'=4, which is consistent with the results of recent hydrostatic compression experiments and theoretical calculations.
