Abstract
- In this study, 0.5Ca 0.15 Sr 1.85 Bi 4 Ti 5 O 18 (CSBT)-0.5BiFeO 3 (BFO) ceramics were synthesized, and the effects of different sintering atmospheres (air and N 2) on their structure and electrical conductivity were reported. According to XRD, TEM, and Raman analyses, the 0.5CSBT-0.5BFO ceramics had a B2cb space group (orthorhombic crystal structure) and an m=5 bismuth layered perovskite structure, except the Bi 2 O 3 second phase (cubic, Pn-3m) is in the air-sintered sample. The XPS analysis results show that the air-sintered sample had a greater hole (h •) concentration than the N 2 -sintered sample. The impedance and conductivity investigation results show that the 0.5CSBT-0.5BFO ceramics had p-type and CBH conduction mechanisms. [ABSTRACT FROM AUTHOR]
