Abstract

Stoichiometric nano sized copper ferrite particles were synthesized by sol gel combustion technique. They were then calcined at various temperatures ranging from 300–800°C and were either furnace cooled or quenched in liquid nitrogen. A high magnetisation value of 48.2emu/g signifying the cubic phase of copper ferrite, was obtained for sample quenched to liquid nitrogen temperature from 800°C. The ethanol sensing response of the samples was studied and a maximum of 86% response was obtained for 500ppm ethanol in the case of a furnace cooled sample calcined at 800°C. The chemical sensing is seen to be correlated with the c/a ratio and is best in the case of tetragonal copper ferrite.
