| Abstract: | Ba6-3xNd8+2xTi18O54 ceramic powders have been synthesized by the Pechini method. The precursors and derived oxide powders were characterized by DTA, TG, XRD and TEM. The effect of the molar ratio of citric acid to total metal cation concentration on the crystallization behavior of Ba6-3xNd8+2xTi18O54 was investigated. Single-phase and well crystallized Ba6-3xNd8+2xTi18O54 powders were obtained from pulverized resin at 900 °C for 3 h, without the formation of any intermediate phase, when the correct molar ratio of citric acid to total metal cations concentration is used. |
