Polymeric precursor synthesis of Ba6–3xSm8+2xTi18O54 ceramic powder

Ba6–3xSm8+2xTi18O54 ceramic powders were synthesized by the polymeric precursor method using ethylenediaminetetraacetic acids as chelating agent and ethanol glycol as esterification agent. DTA-TG, XRD and SEM were used to characterize the precursors and derived oxide powders. Powders calcined at 700 °C were found to be amorphous, but well-crystallized Ba6–3xSm8+2xTi18O54 was obtained at temperature of 1000 °C for 3 h with the primary size of about 100–200 nm.
