Abstract

In the Y₂O₃–Al₂O₃–B₂O₃ system, homogeneous glasses were obtained from compositions containing from 50 to 65 mol% B₂O₃. The density, refractive index, and thermal expansion increase as Y₂O₃ replaces either B₂O₃ or Al₂O₃. These glasses have a dilatometric softening temperature above 665°C, and below 300°C their dc electrical resistivity exceeds that of fused silica. The infrared absorption spectra indicate that BO₃, BO₄, and AlO₄, groups are present in these glasses.
