The February 2026 issue 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 second issue of the 2026 monthly scientific and technical journal Glass and Ceramics.

Contents of the February issue:

— A STUDY OF THE DEGRADATION OF THE LUMINESCENT PROPERTIES OF ERBIUM-DOPED ZINC-TELLURITE GLASSES UNDER TROPICAL CONDITIONS

Glasses in the TeO2–ZnO system doped with Er3+, Yb3+, and Nd3+ were studied. The effect of the synthesis atmosphere on the properties of the resulting glasses was determined. The photoluminescence intensity, absorption, refractive index, and chemical purity of the glasses were experimentally determined. The stability of the spectral and luminescent properties under the tropical climate of Southeast Asia was studied.

— TECHNOLOGY FOR PRODUCING GRANULATED FERTILIZER BASED ON PHOSPHATE FOAM GLASS

The paper presents results substantiating the feasibility of developing an industrial technology for producing granulated mineral fertilizer based on phosphate foam glass. It has been established that phosphate foam glasses, with their slow solubility and ability to improve soil physical properties, are promising fertilizers for agricultural crops. A raw material batch for melting phosphate glass has been developed, including monopotassium phosphate (MKP), apatite concentrate from the Khibiny deposit (AKKh), and orthophosphoric acid (OPA). Phosphate glass was melted at 900°C, yielding an amorphous glassy product with a P2O5 content of 59.88%. Based on the resulting product, phosphate foam glass samples were synthesized with varying amounts of a gas-generating additive—dolomite flour (DM). The optimal DM content was found to be 6%. Phosphate foam glass granules with the optimal DM content were synthesized using a tubular rotary kiln. The resulting granules had a bulk density of 222 kg/m3.
