The dynamics of crystallization in barium borate glasses is reported. The glasses of 50BaO-50B2O3 and 48BaO-48B2O3-4TiO2 were investigated. β-phase BaB2O4 microcrystals were formed by the heat treatment. The Time-Temperature-Transformation diagrams of these two glasses were obtained. It was found that 48BaO-48B2O3-4TiO2 glass was more stable than 50BaO-50B2O3 glass. The obtained diagram will be useful for the development and practical fabrication of the crystallized barium borate glasses.
