Study of Properties of Model Borosilicate Glasses with Various Contents of a Cesium–Strontium Fraction for the Development of Technical Requirements

Model borosilicate glasses of four compositions with different contents of the cesium–strontium fraction are synthesized. The following properties of glass are studied: melting temperature, glass density, compressive strength, homogeneity, and thermal and chemical resistance. Based on the obtained experimental data, technical requirements are developed for samples of a solidified short-lived fraction of high-level waste (HLW).
