Praseodymium, lanthanum indates solid solutions Pr1–xLaxInO3 were synthesized by ceramic me- thod for the first time. It was found that in PrInO3 – LaInO3 binary system there was a continuous range of praseodymium-lanthanum indates solid solutions Pr1–xLaxInO3 with the structure of orthorhombically distorted perovskite. Thermal elongation of synthesized samples was investigated in 400–1,120 K tem- perature range. Сomplex thermal analysis of the samples synthesized was carried out up to 1,273 K. Temperature dependences of relative elongation had no anomalies due to the phase transitions and us- ing these dependences average linear coefficients of thermal elongation were calculated by least- squares technique. On the differential scanning calorimetry (DSC) curves for all the samples investi- gated no thermal effects were observed.
