Title: Microwave assisted combustion synthesis of nanocrystalline CoFe{sub 2}O{sub 4} for LPG sensing

A microwave-assisted citrate precursor method has been utilized for synthesis of nanocrystalline powders of CoFe{sub 2}O{sub 4}. The process takes only a few minutes to obtain as-synthesized CoFe{sub 2}O{sub 4}. Structural properties of the synthesized material were investigated by X-ray diffraction; scanning electron microscopy, Thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy. The gas sensing properties of thick film of CoFe{sub 2}O{sub 4} prepared by screen printing towards Liquid Petroleum Gas (LPG) revealed that CoFe{sub 2}O{sub 4} thick films are sensitive and shows maximum sensitivity at 350°C for 2500 ppm of LPG.
