摘要：

The glass transition temperatures and the thermal expansion coefficients below and above the glass transition range are determined for barium aluminoborate glasses over a wide range of compositions containing up to 60 mol % BaO and 35 mol % Al2O3. The behavior of these characteristics is studied depending on the Al2O3 concentration at constant BaO/B2O3 ratios (from 0.2 to 1) and upon replacement of B2O3 by BaO at constant Al2O3 Contents (up to 30 mol %). The influence of composition on the properties is interpreted within the concepts of the barium aluminoborate glass structure.
