Lithium barium borate glasses of composition defined as series I : 30 Li 2 O - X BaO - (70 – X) B 2 O 3 (where X = 0, 5, 10, 15 and 20 mol %) and series II : (30 – X) Li 2 O - X BaO - 70 B 2 O 3 (where X = 0, 5, 7.5, 10, 12.5 and 15 mol %) have been studied for their density, the coefficient of thermal expansion, CTE, glass transition temperature, Tg and electrical conductivity. An attempt is made to correlate the observed variations in these properties with the Li+ ion content, mass and the field strength of the Ba 2+ cations and corresponding changes in the network. The studied glasses offer a very good range of CTE (72 - 112 x 10 −7 / K) and could be developed as electrical insulators on account of their poor electrical conductivity..
