Реферат:	eng: Crystallization of glass samples with compositions of 20MnNbOF(5)-40BaF(2)-40BiF(3), 20MnNbOF(5)-30BaF(2)-50BiF(3), and 30MnNbOF(5)-30BaF(2)-40BiF(3) has been studied using Raman spectroscopy. The study of band formation kinetics in high-frequency and low-frequency regions of the Raman spectrum provided information about the crystallization of the materials. The processes involved in glass crystallization have been found to be strongly dependent on the glass composition and annealing schedule. For 20MnNbOF(5)-40BaF(2)-40BiF(3) and 20MnNbOF(5)-30BaF(2)-50BiF(3) glasses, crystallization is accompanied by liquation, whereas for 30MnNbOF(5)-30BaF(2)-40BiF(3) glass, crystallization does not involve noticeable liquation effects and occurs in one step.
