Figure 4
Pressure dependence of the unit-cell volumes of the different phases of Rb2S. As shown in the insert, solid squares, circles and stars represent V–P data points corresponding to the antifluorite-, anticotunnite and Ni2In-type phases, respectively. The EOSs fitted are also illustrated as solid and dashed lines for the anticotunnite-type and the Ni2In-type phases. |
