The degree of the baddeleyite-corundum refractories erosion depending on the areas of their location in the glass-making furnace in the float glass production was established. With the use of petrographic analysis the influence of chemical and mineral composition and also temperature and gas environment on corrosion of bacor linings was studied. Due to obtained results the recommendations in relation to the increase of glass-attack resistance of the furnace and its service life length were formulated.

Three Phases

A part of a soldier block, placed in a float glass furnace near the hot spot area, was investigated to learn about the changes in the microstructure during the production of the block, during the use for glass melting and after the shut down of the furnace and the cooling of the block. Beside the three phases after the production (baddeleyite, corundum, vitreous phase) during use as a soldier block mullite and secondary corundum as well as secondary zirconia may occure. Cooling down the used block after the furnace campaign the beginning of the crystallisation of feldspars may be seen.

Multilayered nanocoatings allow outstanding properties with broad potential for glazing applications. Here, we report on the development of a multilayer nanocoating for zinc oxide (ZnO) and antimony doped tin oxide (ATO). The combination of ZnO and ATO thin films with their promising optical properties is a cost-efficient alternative for the production of energy-efficient glazing. It is an effective modification of the building envelope to reduce current high domestic demand of electrical power for air conditioning, especially in hot climates like Saudi Arabia. In this paper, we report the development of a nanocoating based on the combination of ZnO and ATO. Principle material and film investigations were carried out on lab-scale by dip coating with chemical solution deposition (CSD), while with regard to production processes, chemical vapor deposition (CVD) processes were evaluated in a second stage of the film development. It was found that with both processes, high-quality thin films and multilayer coatings with outstanding optical properties can be prepared. While keeping the optical transmission in the visible range at around 80%, only 10% of the NIR (near infrared) and below 1% of UV (ultraviolet) light passes these coatings. However, in contrast to CSD, the CVD process allows a free combination of the multilayer film sequence, which is of high relevance for production processes. Furthermore, it can be potentially integrated in float glass production lines.

The current state of technologies for the production of glass products used in the architectural and construction industry, types of the energy-saving float-glasses and their role in the lighting quality of the buildings was analyzed. The relevance of the use of Low-E glass, in particular in the glass units, is shown. Innovative trends in the production of sheet architectural and construction float glass with the use of modern technologies and equipment, in particular, at PJSC "Lysychansk glass factory "Proletary ", considered. It is established that a significant disadvantage of more energy-efficient I-glasses, which have a wide range of color characteristics, is the insufficient mechanical strength of soft coatings applied by magnetron vacuum spraying. It is shown that the technology of manufacturing low-emission I-glasses with such coatings does not allow them to be hardened while maintaining all the necessary operating parameters. Physicochemical properties and operational characteristics of large-sized glasses with silver, sunscreen soft coating, laminated, flat and radial tempered glasses, as well as their areas of application are presented. The principles of strengthening soft magnetron coatings for low-emission Double Low-E glasses and composition, layer combinations and technological parameters of multilayer nanocoatings with a total thickness of up to 140 nm, which allows to harden I-glass with these coatings, investigated. The technological parameters of obtaining low-emission I-glasses with variable coatings, which regulate the spectral and operational indicators of these glassware according to the interstate standards GOST EN 673-2016 and GOST EN 410-2014, are analyzed. Technological methods of the sheet glass with low-emission coatings hardening by creating of the special compositions and optimizing magnetron sputtering processes optimizing, as well as the basic regularities of the arrangement of the film layers of the Si3N4 / NiCr / Si3N4 film for the heat treatment withstanding of the glasses in the R2O – RO – SiO2 system are considered. The principles of adjusting their spectral and mechanical characteristics depending on the concentration and ratio of the components of the thin-film nanolayer, which will contribute to the creation of a variation series of float glasses with the required level of reflection in the infrared spectrum, are proposed.

During archaeological research in the cremation cemetery in Żelazna Nowa, 106 glass and four faience artefacts were uncovered. Most of them were found in eleven cremation burials (1, 2, 19A, 33, 34, vicinity of 36, 37, 39, 44, 47, 54) dated between the 1st and 3rd centuries AD. The glass pieces are highly fragmented, melted, or fused with other elements of the pyre, with only one glass bead completely preserved (type 218c acc. to Tempelmann-Mączyńska). The faience objects have survived in better shape: these are two complete beads and two fragments, all representing type 171 (acc. to Tempelmann-Mączyńska). Chemical compositions of 12 glass pieces and one fragment of a faience bead were determined using EPMA analysis. All the analysed artefacts turned out to be sodium glasses, made using both mineral sodium (natron) and sodium from the ash of halophytic plants (one sample). Natron glasses represent three groups distinguished by varying contents of MgO and K2O. The differences in concentrations of these components indicate that sands from different deposits were added in the glass-making process. This corroborates a hypothesis positing multiple centres of glass production during the Roman Period.
