The aim of the research is to develop compositions of high-temperature radiopaque ceramics based on strontium or barium aluminosilicate compositions with increased corrosion resistance and durability and with specified dielectric characteristics. Research methods - methods of mathematical modeling and experimental studies of physical and mechanical, dielectric properties and chemical stability of ceramic materials. The following scientific results were obtained: - comprehensive studies of the properties of the developed material, which determine its efficiency in operating conditions - technological parameters of obtaining high-temperature radio-transparent ceramic materials based on strontium and barium aluminosilicates with increased corrosion resistance and durability have been developed; - experimental samples were made and their dielectric properties at ultrahigh frequencies were studied; - practical recommendations on the use of research results were developed and the implementation of SC "Ukroboronprom" KDNVP "Kvarsit" was carried out. 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.
