摘要：

The glass‐formation region of the calcia‐gallia‐silica system was determined. The glasses within this region were measured to have a density of 3 to 4 g/cm3, a refractive index of 1.6 to 1.73, an Abbe number between 35 and 58, a thermal expansion coefficient of 6.5 × 10−7/°C to 11.5 × 10−7/°C, softening temperatures between 730° and 790°C, and a Vickers microhardness of 5.2 to 7.3 GPa. Crystalline phases were identified along the glass‐formation boundary. Infrared transmission spectra were used to explain glass structures and their effect on glass properties. The results suggest that the role of calcia in the glass structure is similar to that for calcia in calcium aluminosilicate glasses. Copyright © 1990, Wiley Blackwell. All rights reserved
