Effect of In₂O₃ Doping on the Gas Sensitivity of ZnFe₂O₄

Department of Materials Science and Engineering, China University of Science and Technology, Hefei 230026

Received Date: 29 April 1998
Revised Date: 14 October 1998

In₂O₃ has been doped in ZnFe₂O₄ by a chemical coprecipitation method. XRD results showed that in doped system there is no new phase formed and only a little change in lattice constants. Doping of In₂O₃ decreased the conductivity of ZnFe₂O₄ sensor, changed its conduction mechanism and increased its response to C₂H₅OH.
