## Abstract Raman spectra of molten Sm~0.8~La~0.2~AlO~3~ have been recorded from room temperature to 1470 K. Experimental results show that a firstβorder phase transition occurs at 580 K and that two phonon modes appear very unstable in the high temperature phase. Comparison with Raman data obtaine
