【 摘 要 】

NdFeO3is one of the oxide material can be detected various gases, like S/O2, CO, H2S, etc. In this research, Nd1.2FeO3as oxide material have been synthesized by solid-state reaction with a variation of annealing time. Characterized by XRD shows that the samples have form crystal perovskite structure with dominant phase and peak intensity correspond to hkl (121). FWHM value for the dominant peak was 0.22°. The crystallite of the samples was determined using Debye Scherer formula were 393.08, 393.10, and 393.10 nm, respectively. While the SEM characterized showed the morphology of the samples was homogenous with grain size estimates of 0.2μm. These results indicate the variation of annealing time 1, 2, and 3 hours did not significantly affect the crystallinity and morphology of Nd1.2FeO3oxide material.
