The aim is to develop theoretical and technological principles receipt radio ceramic compositions based systems RO - RO2 - Al2O3 - SiO2 (where RO - BaO, SrO, ZnO; RO2 - TiO2) with the participation of s-, p- and d-elements positively affect the molecular structure of ceramics, contribute to the formation of a given phase composition and structure of high-density materials that have set high functional characteristics and performance properties. Methods of research - theoretical calculations in the diagrams of the state of oxide systems; forecasting of the phase composition and properties of compositions; research of physical-mechanical, electrophysical and chemical properties of ceramic materials.New data were obtained in multicomponent oxide systems: minimum eutectic temperatures, conod lengths and phase coexistence possibilities were found; the field of existence and the figurative points of composition compositions. Investigated low-investigated areas in the system RO-RO2-Al2O3-SiO2 and investigated the influence on the phase composition, structure and functional properties of ceramic and glass crystalline materials of oxides s-, p- and d-elements.
