Abstract: 5 % Y3+ added Mg1-xCdx Fe2O4 (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) nanocrystallite samples were synthesized by oxalate co-precipitation method and studied for gas sensing properties. These samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The XRD confirms cubic spinel structure with orthoferrite (YFeO3) secondary phase. The crystallite size lies in the range of 28.86 to 32.06 nm. The SEM study revealed that the average grain size is in the range of 0.37 to 0.69 m. The FT-IR spectra showed two strong absorption peaks around 350-800 cm-1. The highest sensitivity to LPG and Cl2 (85 % and 79 % respectively) appears for Y-Mg ferrite sensor at 218 oC. The highest sensitivity (89 %) to ethanol appears for Y-Cd ferrite sensor at 325 oC. The Y-Mg0.6Cd0.4Fe2O4 sensor shows good sensitivity to LPG followed by Cl2 and ethanol (82 %, 77 % and 70 % respectively) at 190 oC. The addition of 5 % Y3+ in Mg-Cd ferrites enhances sensitivity and reduces response-recovery time and operating temperature. The sensing properties for LPG, Cl2 and ethanol change with the operating temperature, composition, porosity and grain size.
