Keywords:crystallized glass, TTT diagram, barium borate glass

TTT diagrams of barium borate glasses were obtained. b-BBO micro crystals were formed in barium borate glasses with heat treatment for the crystallizartion. We examined 48BaO-48B2O3-4TiO2 and 50BaO-50B2O3 glass, and it is suggested that TiO2 makes the glass stable.
