Abstract:Compound oxide CoFe2O4 powder with spinel structure was synthesized with solution of soluble cobalt and iron salt which are under given Mole proportion and hydroxide as precipitator by chemical co-precipitation. The gas-sensing properties of the CoFe2O4 are studied and the results reveal that the gas sensors based on CoFe2O4 which is heater type and thick film have a high sensitivity to ethanol, acetone and acetic acid without doping.
Keywords:CoFe2O4
