High Pressure X-Ray Diffraction Studies of UX3 (X = Al, Si, Ga, Ge, In, Sn)

Several intermetallic uranium compounds UX3 (X = Al, Si, Ga, Ge, In, Sn) were studied under high pressure up to ca. 40 GPa (except UGa3 up to 80 GPa) using a diamond anvil cell and energy dispersive X-ray diffraction facilities. The compounds which have the cubic AuCu3 structure, do not show any crystallographic phase transition in the domain of investigation.JRC.E-Institute for Transuranium Elements (Karlsruhe
