Description

Differential thermal analysis and visual polythermal analysis are used to study phase equilibria in the BaO-BaB2O4 system. The following compounds are formed in the system: Ba5B4O11 (which melts peritectically at 1170 ± 10 deg C), Ba3B2O6 (which melts congruently at 1390 ± 10 deg C), and Ba4B2O7 (which decomposes in the solid state at 1190 ± 10 deg C)

Abstract (Russian)

Методами дифференциального термического и визуально-политермического анализов изучены фазовые равновесия в системе ВаО-ВаВ2O4. В системе образуются соединения Ва5В4O11 (плавится по перитектической реакции при 1170 ± 10 град С), Ва3В2O6 (конгруэнтно плавится при 1390 ± 10 град С) и Ва4В2O7 (разлагается в твердом состоянии при 1190 ± 10 град С)
