Heavy metal Ñuoride glass ZBLAN, with molar composition ZrF 4 (53)-BaF 2 (20)-LaF 3 (4)-AlF 3 (3)-NaF(20), was studied in vacuum at high temperatures up to 480 ÄC by Raman spectroscopy. The vitreous glass was found to crystallize at 330 ÄC, most probably to crystallites. High-temperature experiments
