Abstract
Sr0.7Ba0.3Nb2O6 ceramics (SBN70) were prepared by using conventional sintering techniques from nitrate precursor (NSBN70) and carbonate precursor (CSBN70). The sintering behavior and structures evolution of NSBN70 was characterized of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effect of precursors on the sintering behaviors and structure evolutions was studied. SBN70 from nitrate precursors is produced at 1400°C for 4h or 1375°CC for 6 h. SBN70 from nitrate precursors showed a duplex microstructure. Abnormal grain growth occurs more easily than SBN70 from carbonate precursors.
