Title

Glass Formation and Properties in the Gallia-Calcia System

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, nD, 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.
