Properties of Yttria-Aluminoborate Glasses
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.
