The rare-earth and actinide based compounds are endowed with several exotic physical and chemical properties due to the presence of -electrons. These properties exhibit interesting changes under the action of various thermodynamic fields and hence continues to be a subject of extensive research. For instance, under pressure, the nature of -electrons can be changed from localized to itinerant, leading to a variety of changes in their structural, physical and chemical properties. The present review on the high pressure phase transition behaviour of dialuminides of rare earths and actinides is an outcome of research in our laboratory during the last five years using a unique combination of a Guinier diffractometer and a diamond anvil cell built in-house. To bring out the correlations between the compressibility and structural behaviour with the electronic structure, we have also carried out electronic structure calculation. Further, the usefulness of Villars' three parameter structure maps in predicting pressure induced structural transitions has been explored and this has been illustrated with the available phase transition data.

“…However, no such systematic studies have been done on their AB ¾ type intermetallic compounds. Table 1 lists some of the AB ¾ type intermetallics which have been studied under high pressure so far [11][12][13][14][15][16][17][18].…”

“…-A first series of measurements was made at the CNRS in Grenoble up to 13 GPa using a diamond anvil high pressure X-ray apparatus. A high power rotating anode was used to increase the X-ray flux [7]. NaCI was used as a marker and classical diffraction patterns were recorded by the Debye-Scherrer method.…”

2014 Le comportement du bioxyde d'uranium sous des pressions jusqu'à 40 GPa a été étudié par diffraction X sur poudre dans des cellules à enclumes de diamant. L'oxyde cfc se transforme progressivement en UO2 II, phase moins symétrique, entre 29 et 38 GPa. Lorsqu'on diminue la pression, la transformation inverse se fait seulement entre 15 et 5 GPa. Il s'agit probablement d'une transformation purement structurale qui n'est pas liée à une délocalisation d'électrons 5f.Abstract. 2014 Uranium dioxide was studied by X-ray powder diffraction under pressure in diamond anvil cells up to 40 GPa. A gradual transition to a low symmetry high pressure phase (UO2 II) occurs in the range 29 to 38 GPa. On pressure release, UO2 II is conserved by hysteresis below 15 GPa, but retransforms completely to fcc UO2 I above 5 GPa. The transformation is likely to be a purely structural one which is not due to delocalization of 5f electrons.
