Citrate–nitrate combustion route to the synthesis of (1−x)LaCrO3xBiCrO3 solid solution

Solid solution of (1−x)LaCrO3xBiCrO3 (x = 0, 0.10, 0.15, 0.20 and 0.25) was prepared via the citrate–nitrate combustion synthesis. Pure perovskite phase was obtained at 800 °C, a much lower synthesis temperature than that needed in the solid-state reactions. The thermodynamics of phase formation and the ceramic sintering mechanism were investigated. The substitution of Bi3+ for La3+ was found to give a separate exothermic decomposition event in the gels and the precursor did not produce a transient liquid phase while heating to 1200 °C, as was found in ceramics prepared by solid state reaction. This finding shows that the role of Bi2O3 in the sintering of the La1−xBixCrO3 ceramics depends on the processing method.
