The magazine «Glass and Ceramics» for May 2024 has been published

Dear Colleagues!

Viktor Osipov, President of the Association "StekloSouz" of Russia, is a member of the Editorial Board of the Glass and Ceramics magazine.

We inform you that the 5th issue of the monthly scientific and technical magazine “Glass and Ceramics” for 2024 has been published.

Contents of the March issue:

✔ MATERIALS BASED ON 45S5 BIGLASS, DOPED WITH HEAVY ELEMENTS, FOR USE AS RADIOSENSITIZERS

Glass and glass ceramics containing oxides of heavy metals (Bi, Ta, W) in an amount of 40 wt. were obtained. %, for use in medicine as radiosensitizers. The properties of the composites were studied in vitro: generation of secondary radiation, chemical solubility, change in pH of the medium during resorption. The indicators of secondary radiation and the pH value of the medium decrease in the series W > Ta > Bi, solubility indicators - in the series W > Bi > Ta. Despite the maximum generation of secondary ionizing radiation, W-containing ceramics based on Bioglass 45S5 bioglass are undesirable for use in vivo due to rapid dissolution and high alkalization of the environment.

✔ DEVELOPMENT OF COLORED GLASS COMPOSITIONS BASED ON BASALT OF THE OSMONSAY DEPOSIT

The development of compositions of colored glasses based on basalt from the Osmonsay deposit is presented. To synthesize glasses, compositions in the basalt–quartz–soda system were studied. Quartz sand from the Samarkand deposit was used as a source of quartz. Transparent, translucent and opacified colored glasses were obtained. As a result of the research, it was established that it is possible to obtain glass in a wide range of colors without the use of coloring components.
