Beschreibungen/Notizen

• The glass-forming region in the calcia-gallia-silica system is studied and found to be fairly large, with a density of 3-4 g/cu cm, a refractive index of 1.6-1.73, an Abbe number of 35-58, a thermal expansion coefficient of 6.5-11.5 x 10 to the -7th/deg C, and a Vickers microhardness of 5.2-7.3 GPa. Crystalline phases are identified at the boundary of the glass-forming region. The structural groups in the glass-forming compositions are analyzed by infrared absorption spectroscopy.
