Glass Formation and Glass-Forming Ability of Melts in AIIO–B2O3Binary Systems (AIIO = BeO, MgO, CaO, SrO, BaO, ZnO, CdO)

Abstract

The data on the sizes of glass formation regions in the AIIO–B2O3 binary systems (where AII is a Group IIA or IIB element of the periodic table) and the possibility of calculating the glass-forming ability of simple oxides with the use of the Sun and Rawson criteria are analyzed. The disadvantages and limitations of these criteria are discussed. The modified Sun–Rawson criterion is described, and the glass-forming ability of melts in the AIIO–B2O3 systems is calculated according to this criterion. The possibility of forming glasses in the BaO–B2O3, SrO–B2O3, and CdO–B2O3 systems is predicted in the composition regions for which data on the glass formation are not available.
