Summary:Partial sections of the system BaO-La^sub 2^O3-B^sub 2^O3-TiO2-SiO2 were studied and the regions of glassy-state stability are determined. The regular effects of titanium, lanthanum, and barium oxides on the crystallizability of the experimental glasses and on the optical and thermal properties were established. An optical glass with refractive index 1.81, average dispersion 0.0187, and CLTE 76.8×10^sup -7^ K^sup -1^ was obtained. This glass can be recommended for high refractive-index optical lenses as well as for the light-guiding core in optical fibers.[PUBLICATION ABSTRACT]
