The paper considered promises for creation of radio-ceramic ternary SrO-Al2O3-SiO2. Predictive analysis on capabilities of synthesis of radiotransparent ceramic strontium anorthite non-stoichiometric composition was conducted with the help of theoretical research. By grapho-analysis of selected compounds there were determined the start temperature and complete melting temperature, phase composition, and the amount and chemical composition of the melt, which are formed at predetermined heat treatment conditions. Also, for creation of the radio-transparent material its dielectric characteristics and the glass phase material was calculated and the low temperature ceramic composition were recommended.

strontium feldspar, dielectric permittivity, liquidus temperature, melt, glass phase.
