Abstract

The critical cooling rate for glass formation was measured for five compositions in the Ga₂O₃-CaO system and varied from a low of (315 ± 85) °C/s for a eutectic melt containing 37.5 mol.% Ga₂O₃ to a high of (840±60)°C/sec for a melt containing 52 mol.% Ga₂O₃. Selected properties of glasses containing from 37.5 to 62 mol.% Ga₂O₃ were measured. The density and refractive index, n_D, both increased with increasing Ga₂O₃ content, but the crysallization temperature and microhardness varied only slightly with Ga₂O₃ content. The IR spectra of these glasses suggest that both GaO₄ tetrahedra and GaO₆ octahedra are present.
