| description | In the present work the synthesis of materials was carried out by one-step citrate-nitrate method. The optimal synthesis temperature of the powders was chosen on the base of TG-DSC data. Phase nature of the synthesized materials was investigated by XRD and Rietveld refinement data analyzes. The influence of the perovskite phase content in the system of (1-x)Ce0.8Nd0.2O2-δ-xBaCe0.8Nd0.2O3-δ ( x = 0 , 0.25, 0.5 , 0.75 and 1) on the crystallite and particle size of powders and structure properties of ceramics (relative density, porosity, grain size) were investigated. Measurements of the electrical conductivity of materials in a wide ranges of temperatures (550-900 °C) and oxygen partial pressure (10-23≤pO2/atm≤0,21) revealed features of transport in the composite system. |
