This paper describes an analysis based on a study of the changes in density, refractive index, the dilatometric characteristics, liquidus temperature, electrical conductivity, viscosity, and the activation parameters for glasses of the ZnO-CdO-B/sub 2/O/sub 3/ system with a constant concentration of B/sub 2/O/sub 3/. The study showed that with an equimolar replacement of ZnO by CdO, the different effect of the nature of Zn/sup +/ and Cd/sup 2 +/ cations on the properties of the glasses is determined by the different degree of covalency (ionicity) of the cation-ligand bonds. The low-melting region in the middle range of glass compositions is explained by the similarity between the structural motifs of the glasses and of the ternary compound ZnO.2CdO.2B/sub 2/O/sub 3/ which has a comparatively low melting point by comparison with cadmium and zinc borates which crystallized in glasses rich in these cations. Glassy materials based on binary borate systems are used in the production of electrovacuum glasses, and some melts of alkaline-earth metals are used to grow single crystals of high-melting oxides.
