Abstract
A series of La₂O₃-added zincborosilicate glasses was fabricated by systematically varying La₂O₃ addition up to 15 mol% under the constraint of a ZnO:B₂O₃ ratio of 1 : 2. The degree of water leaching after ball milling of the prepared glasses in water medium was relatively quantified by the change in zinc peak intensity in energy dispersive spectroscopy. 8mol% of La₂O₃ was the most efficient addition in inhibiting the glass leaching by water. The role of La₂O₃ in inhibiting the leaching was explained in terms of change of structural units in the glass network. When the optimum 8 mol% La₂O₃-added ZnO-B₂O₃ glass was used as sintering aid for Al₂O₃, the fabricated alumina-glass composite at 875℃ demonstrated dielectric constant of 6.11 and quality factor of 15470 ㎓, indicating the potential of leaching-minimized La₂O₃-ZnO-B₂O₃ glass for application to low temperature co-fir-ing ceramic technology.
