Аннотация:The synthesis of Nd2-xCaxCoO4 +/-delta at T=900-1200 degrees C in air at atmospheric pressure was performed by solid state synthesis and freeze drying synthesis methods. Single phase solid solutions were observed at 0.6 <= x <= 1 and T=1200 degrees C. At T<1100 degrees C the range of solid solutions formation was drastically reduced to 0.9<x<1.05. Exact position of solid solution domain boundaries is varied with synthesis method that points to the exceptional influence of kinetic factors on the phase formation processes. (C) 2012 Elsevier B.V.
