Development of compositions and physico-chemical bases of energy-saving technology of a new class of domestic ultra-high-frequency radio-transparent ceramics and low-melting glasses based on the RO – R2O3 – SiO2 system (R2+ = Ba, Sr, Pb, Zn; R3+ = Al, B, Bi), which possess a complex of special properties and are used for the manufacture and protection of products of rocket and aviation equipment, as well as elements of radio-electronic systems.

The object of research are physical, chemical and technological processes of obtaining glasses for radio-transparent ceramic materials and fusible glasses for soldering with a given set of physical and technical properties.
The purpose of the study is to develop glass compositions for producing radiotransparent ceramics and fusible link solders for rocket and aviation equipment, as well as elements of radio electronic systems.
Research methods are computational and basic physical and chemical methods of analysis.
The influence of the chemical composition of glasses in the PbO-Bi2O3-B2O3-SiO2 system on their basic thermal and physical properties and structural features of their structure was determined.
Thermodynamic calculations have determined the conditions for the formation of the celzian and strontium-anorthite crystal phases for reactions at the triple eutectic points of the BaO(SrO)-Al2O3-SiO2 system. The choice of glass in the BaO(SrO) - Al2O3 - SiO2 system with the lowest cooking temperature for the further manufacture of low-temperature celzian (strontium-anorthite) radiopaque ceramics is substantiated. The chemical composition of glass for celzian radiotransparent ceramics was developed. The chemical composition of glass for strontium-anorthite radiotransparent ceramics has been developed.
Areas of application: C 23.44 Manufacture of other ceramic products for technical purposes; C 23.19 Manufacture and processing of other glass products, including technical products; C 30.30 Manufacture of aeronautical and space aircraft, related equipment; C 26.51 Manufacture of instruments and equipment for measuring, testing and navigation
