abstract={In the present work, thick film of zinc niobium oxide was prepared by screen printing technology and its LPG sensing properties were investigated. The structural and surface morphological characterizations of the material were analyzed by using X-ray diffraction (XRD) and Scanning electron microscopy (SEM). The minimum crystallite size of ZnNb<SUB>2</SUB>O<SUB>6 </SUB>calculated from Scherrer¡¯s formula was found to be 25 nm. SEM images exhibit the porous nature of sensing material with a number of active sites. The average size of pores of nanocomposite ZnNb<SUB>2</SUB>O<SUB>6</SUB> was found to be 4 ¦̀m. The LPG sensing properties of the film were investigated at room temperature 26C for different vol% of LPG. The variations in electrical resistance of the film were measured with the exposure of LPG as a function of time. The maximum value of sensitivity was found 4.8 for 4 vol. % of LPG. These experimental results show that ZnNb<SUB>2</SUB>O<SUB>6</SUB> nanocomposite<SUB> </SUB>is a capable material for LPG sensor.},
