Effect of Sintering Temperature on the Microstructure and Mechanical Property of SrFe_0.9Ti_0.1O_3--SDC Ceramic Perovskite

Sintering temperature effects on perovskite ceramic SrFe0.9Ti0.1O3-delta-SDC was investigated in this research. A fact that the sintering process was carried out to reduce the porosity in the materials that have been pressed. Three different temperatures used in this research range from 1200, 1250, and 1300 degrees C. The button cell was developed from the ceramic material SDC with 5MPa pressure. 5SrFe(0.9)Ti(0.1)O(3-delta)-5SDC ink was printed on top of the button cell on each side to build a symmetrical cell with a configuration electrode/electrolyte/electrode. All symmetrical cells were sintered at 3 different temperatures. Physical and morphology were studied. It was found that symmetrical cells with different sintering temperatures show a different character. The porosity tends to decrease up to 24.38% with the increase of sintering temperature, therefore, increasing the agglomeration and decreasing the strength of the materials. In this study, the material 5SrFe(0.9)Ti(0.1)O(3-delta)-5SDC is suitable to sinter at 1250 degrees C and gives the best porosity, aggregation rate, and density while providing a good endurance.
