The aim is to develop compositions of high-temperature radio-transparent ceramics based on strontium or barium aluminosilicate compositions with specified dielectric characteristics. Research methods - methods of mathematical modeling and experimental studies of physical-mechanical, dielectric properties of ceramic materials. To achieve this goal the following tasks are solved: - scientifically substantiated the choice of compositions promising for the synthesis of high-temperature radio-transparent ceramic materials; - the influence of eutectic additives from among the oxides of s-, p- and d-elements on the formation of slavsonite and celsian, as well as on the processes of structural and phase formation of high-temperature radio-transparent ceramic materials has been studied; - calculation of gas dynamics parameters and stress-strain state of high-temperature fairing obtained on the basis of developed compositions (strontium or barium aluminosilicates) and technological parameters was performed; Scope - experimental and theoretical developments can be used in the creation of radio-transparent ceramic materials in space, rocket and other fields of radio electronics.  Product Description popup.authors , Kryvobok Ruslan V Bilohubkina Karyna V Voloshchuk Valentyna V Zakharov Artem V Korohodska Alla M Lisachuk George V Pitak Yaroslav M Pylypenko Oleksiy I Prytkina Mariya S Taranenkova Viktoriya V Fedorenko Olena Yu.
