Abstract: 

The phase composition, thermal coefficient of linear expansions (TCLE) and electrical conductivity of (PrXLa1-X)1.85Sr0.15Ni0.9Сu0.1O4 (X=0.0; 0.1; 0.5; 0.9 и 1) (X=0.0; 0.1; 0.5; 0.9 and 1), Pr1-YSrYNiO4 (Y= 0.0; 0.05; 0.1; 0.15; 0.16 and 0.2) and Pr1.84Sr0.16Ni1-ZCuZО4 (Z=0.0; 0.1; 0.5 and 1) are investigated at air in the temperature range 100–1000 °C.The thermal coefficient of linear expansion of (Pr1-XLaX)2-YSrYNi1-ZCuZO4 are in range of (11.6–16.3) 10-6 deg-1 and depends on the size and type of addition. One compositions are compatible on TCLE with electrolytes used in intermediate-temperature electrochemical devices other compositions have TCLE near to TCLE of electrolyte of Zr0.85Y0.15O1.925, that is used in high temperature electrochemical devices. The maximum of conductivity of the most conducting compositions is in the temperature interval of 500–800 °C.
