A high-pressure study of Th(3)P(4) and some U(3)X(4) compounds
The high-pressure crystal structures of Th(3)P(4) and U(3)X(4), where X = P, As and Sb, have been studied by means of synchrotron X-ray diffraction in the pressure range up to 50 GPa. The cubic phase of these compounds is retained in the whole pressure range. The bulk modulus B(0) and its pressure derivative B(0)' have been determined for each compound. A log-log plot of B(0) versus unit-cell volume gives a straight line for the uranium pnictides, with a slope about -5/3.
