The December 2025 edition of the Glass and Ceramics journal has been published

Dear colleagues!

Viktor I. Osipov, President of the Association "StekloSouz" of Russia, is a member of the editorial board of the Glass and Ceramics journal.

We are pleased to announce the publication of the 12th issue of the monthly scientific and technical journal Glass and Ceramics for 2025.

November issue contents:

- MICROMODIFICATION OF SHEET GLASS STRUCTURE WITH FEMTOSECOND LASER PULSES TO CREATE ANALOG SOUND MEDIA

The formation of microregions with modified refractive indices in the bulk of sheet and quartz glass exposed to single femtosecond pulses was studied. Phase distributions of light passing through microregions were plotted, observed along and perpendicular to the recording direction. The effect of pulse energy on the magnitude of phase change was investigated. It was found that the minimum energy for microregion formation in sheet glass is lower than in quartz glass. These results are of interest for the creation of analog sound carriers by modifying the glass structure with femtosecond laser pulses.

- EFFECT OF THERMOCHEMICAL STRENGTHENING OF ALUMINOSILICATE GLASSES ON THEIR OPTICAL AND MECHANICAL PROPERTIES

Thermochemical strengthening processes in aluminosilicate glass were studied. The glass was processed in a KNO3 melt. Under industrial and laboratory conditions at 440–480°C for 1–120 hours. The effect of processing conditions on the glass properties was assessed using Vickers microhardness, spectrophotometry, magnetophotoelasticity to measure compressive stresses, and local birefringence analysis to determine the depth of the compressed layer. X-ray fluorescence was used to evaluate cation exchange. A relationship between the temperature-time parameters of ion exchange and changes in the structural, mechanical, and optical properties of the glass was established.

- DEVELOPMENT OF A TECHNOLOGY FOR THE SYNTHESIS OF HEAT-INSULATING GLASS-CRYSTAL MATERIALS BASED ON DRILLING SLUDGE BY HYDRATE FOAMING

This paper presents the development of a technology for synthesizing slamolite, a heat-insulating glass-crystalline material, based on oil drilling waste. Drill cuttings were sampled at the Komsomolskoye oil and gas condensate field and prepared for further use, including drying and milling. Their chemical and phase compositions were determined, confirming the feasibility of using the waste for synthesizing thermal insulation materials. A series of raw materials for synthesizing slurry stone, as well as temperature and time regimes for calcination, were developed. The physical and chemical properties of the synthesized samples were studied. The optimal composition for slurry stone synthesis was determined: 80% drill cuttings, 15% sodium hydroxide, 5% sodium tetraborate, and 10% water, synthesized at a temperature of 1000°C and having a density of 745.05 kg/m³.
