The effects of compositions and different metal salts on the phase of Ba(Ce,Zr)O3 perovskite ceramics derived from the solid state-reaction, sol-gel and Pechini methods are studied. X-ray diffractometer (XRD) and fourier transform infrared spectroscopy (FTIR) were used to study the phase formation of the compound. It was found that the purity of Yb-doped Ba(Ce,Zr)O3 strongly depends on the stoichiometric compositions and metal salts of the raw materials. A high purity compound at a relatively low temperature was obtained only when the powder of Ba(Ce0.8Zr0.2)0.95Yb0.05O2.975 was prepared from metal nitrate salts. Result of FTIR also confirmed that there was no carbonate species present in the sample prepared by Pechini method after it was sintered at 1400°C.
