Investigation of MgxSr1-xO Mixed Alloy under High Pressure

Purvee Bhardwaj


The structural and mechanical properties of alkaline earth oxides mixed compound MgxSr1-xO (0 ? x ? 1) have been investigated under high pressure. Phase transition pressures are associated with a sudden collapse in volume. Phase transition pressure and associated volume collapses [?V (Pt)/V(0)] calculated from this approach are in good agreement with experiment for the end point members (x=0 and x=1). The results for the mixed crystal counter parts are also in fair agreement with experimental data generated from the application of Vegard’s law to data for the end point members.

Keywords: Mixed crystal, Oxide, Volume collapse, Phase transition, High pressure.
