The research is devoted to the multicomponent system CaTiSiO5-YFeSnO5. The synthesis of solid solutions Ca_1-xY_xTi_1-xSn_xSi_1-xFe_xO₅ (x = 0 - 1.0, Δx = 0.1) was conducted in low-temperature plasma of hydrogen-oxygen flame. It was found that ions Ca²⁺, Ti⁴⁺ and Si⁴⁺ in the molecule of titanit may be substituted with t ions Y³⁺, Fe³⁺ and Sn⁴⁺. In this case, the system produces two phases of variable composition with broad regions of homogeneity. There were defined the boundaries of formed phases, crystallographic and electrical parameters of the solid solutions. All solid solutions have a semiconductor conductivity type, whose value is linearly dependent on the temperature and com- position of the sample.
