Abstract

NdFeO3 is one of the oxide alloys that can be used as a raw material for gas sensor. The NdFeO3 have been synthesized using solid state reaction method by varying calcination temperatures of 750oC, 850oC, and 950oC for 6 h. All of the Nd1.2FeO3 samples were characterized using scanning electron microscope (SEM) and x-ray diffraction (XRD) to identify their morphologies and phases. The results show that all of the samples formed major phase is NdFeO3 and minor phase of Nd2O3 and have homogenous morphology with estimating grain size is 0,2 μm for all samples. The value of FWHM and the crystal size of Nd1.2FeO3 was obtained for each sample is 0.22º and 372 nm. The orthorhombic phase with a dominant peak at hkl (121) is an indication that material has potential application as a gas sensor
