Borate system based low-melting glass

The results of the analysis of systems and areas of application of low-melting glasses based on the literature data used to select the optimal system are presented. The melting properties of low-melting glasses based on the borate system ZnO - SrO - B ₂ O ₃ have been studied. The dependences of the main properties of glasses on the composition (TLEC, temperature of the onset of softening, microhardness, chemical resistance to water) have been established. The optimal compositions of low-melting glasses with the required physicochemical and technological parameters have been determined. Il. 3, bibliography: 7 titles.
