In the Li ₂ O-ZnO-TiO ₂ system, a material with a sintering temperature of 950 ° C has been developed for the technology of low-temperature co-firing of ceramics, which can be used for the production of electronic components... The influence of the content of the sintering additive of the eutectic composition in the Li ₂ O-ZnO-B ₂ O ₃ system, as well as the method of its synthesis on the compaction and dielectric properties of the resulting material. The developed ceramic is characterized by a dielectric constant ? = 17.7 and a dielectric figure of merit equal to 407 MHz

A review of domestic dissertations on ceramics from aluminum oxide, methods of its preparation for the period since 2000 is presented. Thin structural ceramics are mainly considered. The emphasis is on technological aspects. The first part of the review includes sintering Al ₂ O ₃ with additions of heteroelement oxides, reaction sintering with the addition of aluminum, and obtaining cermets of the Al ₂ O _{type 3} -Al, obtaining reinforced composites with an alumina matrix

The results of experiments on studying the properties of a glassy phosphate composition, modernized with copper-containing additives, are presented. The composition is designed to protect the surfaces of many materials from scale deposits, corrosion of metal surfaces, as well as for the treatment of aqueous solutions of organic substances in order to prevent the formation and reproduction of putrefactive bacteria and bacteria involved in eutrophication processes in them (& # 171; bloom & # 187 ;). The use of the composition is recommended for the complex treatment of water for technical and domestic purposes.

Compositions and technological parameters of the synthesis of cellular glass based on ash and slag waste from the Novocherkasskaya SDPP (heat-insulating layer of a multilayer silicate composite heat-insulating and decorative material) have been developed. The physicochemical regularities of the high-temperature formation of the structure of the porous heat-insulating layer of a multilayer silicate composite heat-insulating-decorative material by the methods of DTA, XRD and electron microscopy have been established.

A significant effect of the amount of aluminum-containing nanotechnogenic raw materials based on non-ferrous metallurgy and pyrophyllite on the structural and rheological properties of ceramic masses for the production of acid-resistant materials is shown. The use of nanotechnogenic raw materials improves the physical and mechanical properties of ceramics for acid-resistant materials. Studies have shown that the presence of isometric pores and oval closed porosity, in contrast to elongated (slot-like) pores in ceramic materials, impart mechanical strength to them.

An affordable energy-saving technology of glass-ceramic facing tiles that imitates the texture and main technical parameters of granite has been developed and tested in the laboratory: water absorption less than 1 & # 37;, compressive strength 60 - 70 MPa. Raw mix includes 70 & # 37; mixed irreversible glass breakage. The technological process is distinguished by a high degree of self-sufficiency and flexibility

The results of studies of the physical properties of zeolite raw materials from the Vanginsky field in the Amur region are presented. The structural and adsorption properties of the material modified with HCl have been studied. It is shown that the use of a solution with a concentration of 0.5 M promotes an increase in the adsorption properties

A method for obtaining X-ray contrast bioglass by pyrolysis of organic solutions containing tetraethoxysilane, tributyl phosphate, sodium oleate and calcium oleate in turpentine, as well as tungsten extract in a benzene solution of tri-n-octylamine. The method makes it possible to obtain tungsten-containing X-ray contrast glasses both in the form of powder materials and in the form of coatings on various porous carriers.
