The system Li/Ba/Ca was investigated by transmission electron microscopy (TEM). Three different phases could be identified and characterized. The crystal structure of the previously known compound Li 33.3 Ba 13.1 Ca 3 was confirmed, however, variable calcium contents were observed in distinct crystallites. The same holds for phases with BaLi 4 ‐ and Ba 19 Li 44 ‐type structure, respectively. Structural transformations under irradiation occurred which were different for the crystallites of the Li 33.3 Ba 13.1 Ca 3 ‐ and Ba 19 Li 44 ‐types.
