Popis:	The processes occurring in the glass shells of bactericidal lamps are considered. It is shown that it is expedient to develop new compositions of uviol glasses with elevated radiation and optical resistance (ROR). It was found that an increase in the total amount of alkaline-earth oxides and BaO individually at the expense of CaO +MgO decreases solarization of glasses of the SiO2-MgO-CaO-BaO-Na2O-K2O system. The introduction of Fe2O3 in the composition with a decrease in the content of MgO for a certain concentration of Fe2+ and Fe3+ improves the anti-reflection properties of uviol glasses in the ultraviolet spectral region and increases the ROR to short-wave ultraviolet radiation. Addition of metallic aluminum increases the Fe2+∶Fe3+ ratio. The physicochemical properties of the synthesized compositions are presented.
