摘要：

UC2 has been studied under the general topic of X-ray diffraction analysis of pressure-induced structural transitions in actinide compounds and the determination of their ambient pressure bulk moduli. At 17.6 GPa UC2 shows a phase transition from a tetragonal to a hexagonal structure. The mean values of the bulk modulus and its pressure derivative are 216 GPa and 2.2 respectively.
