TL;DR: In this article, the spectral, optical, physicochemical, radiative, and radiation-shielding properties of glasses in the PbO-P2O5-R�₷  system are investigated as a function of their composition, and a colorless radiation resistant high-lead glass suitable for production on a semicommercial scale is determined.

TL;DR: In this paper, the dependences of the structural strength and the elastic modulus on the chemical composition of phosphate glasses are analyzed, and it is demonstrated that the Young's modulus depends linearly on the total bonding energy per unit volume of the glass.

TL;DR: In this article, the properties of glasses in the Li2O-B2O3-P2O5 system were investigated as a function of the boron oxide content in the range from 5 to 30 mol % at a constant lithium oxide content of 45 mol %.

TL;DR: In this article, the results of the investigation of KGSS 0180/35 neodymium phosphate glasses produced on an industrial scale under oxidizing conditions and glasses prepared under experimental conditions in which iron and copper in small amounts rather than NEmium are introduced into the glass composition are determined.

TL;DR: In this article, a two-stage or single-stage process with high-purity reagents in crucibles made from dispersion-strengthened platinum or a newly developed high-strength cristobalite refractory was developed for the production of large active elements made from KGSS 0180/35 neodymium phosphate glass.
