Microwave dielectric ceramics with the composition of Ca(Zn 1/3 Nb 2/3−x V x )O 3 (CZNV, 0≤x≤0.02) were prepared by the solid-state reaction method. The sintering behavior, phase structure, and microwave dielectric properties of CZNV ceramics were investigated. All samples sintered at 1125–1225°C for 3h remained a single phase. However, the grain shape changed from...
The performance of the LaBaCuFeO 5+δ –Ce 0.8 Sm 0.2 O 1.9 (LBCF–SDC) composite cathodes was studied in this paper. Electrical conductivity, thermal expansion and electrochemical properties were investigated by four probing DC technique, dilatometry, AC impedance and polarization techniques, respectively. The thermal expansion coefficients of the LBCF–SDC were between...
