Barium gallogermanate glasses were prepared with substitutions of Al2O3, Y2O3, La2O3, and Gd2O3 for Ga2O3. The effects of these substitutions on the glass transformation temperature, viscosity, thermal expansion, and molar volume have been determined

The electron spin resonance (ESR) spectra of a series of γ-irradiated calcium aluminosilicate glasses with compositions CaO/Al2O3 = 1.50 and 0–80 mol% SiO2 have been measured at 9.3 GHz. The ESR spectra have been analyzed using spin-Hamiltonian pa

An electron spin resonance investigation of a series of low-silica-content (≤ 20 mol%) calcium aluminosilicate glasses has been performed. The compositional dependence of the X-ray-induced defects is found to be consistent with the proposed depende

Calcium aluminosilicate glasses with small percentages of silica have been prepared. The limits of glass formation at 1600°C were found to expand as silica is added to calcium aluminate base compositions. The behavior of such physical properties as
