Abstract :
We present the crystal structure investigation of CeCuAl3 compound. Our X-ray diffraction study confirms unambiguously BaNiSn3-type structure as the crystal structure of CeCuAl3 in whole temperature range. Moreover, phase transition around 300 °C was found by our high-temperature powder X-ray diffraction measurement. This transition preserves BaNiSn3-type structure, only structural parameters change during the transition. The study is provided on single crystalline and polycrystalline samples as well as on La counterpart to compare mainly high-temperature behavior of these compounds.
