High cesium (Cs)‐bearing sodium borosilicate glasses incorporated with varying concentrations of TiO 2 up to 10 mol% at the expense of B 2 O 3 were prepared by the conventional melt quenching method. Physicochemical properties of the glasses studied include Cs volatilization losses, leaching, and glass transition temperatures. Structural aspects of the glasses were investigated using Fourier transform infrared, 11 B MAS NMR, and UV‐visible optical absorption techniques. From the detailed investigations on these glasses, optimum concentration of TiO 2 for minimum volatilization losses of Cs has been established. Structural studies revealed the role of TiO 2 in the Cs volatilization as well as leaching characteristics of the glass. Based on our studies, it can be inferred that the glass sample with 5 mol% TiO 2 content gives the optimum formulation with regard to the leaching and Cs volatilization losses. Results of the study are useful in the development of high Cs‐bearing glasses for their use as a gamma source for radiation technology application.
