| Abstract: | ZnFe2O4 is a traditional ferrite material. In recent years, it has been found that ZnFe2O4 is also a good gas sensitive material. In this paper, nano ZnFe2O4 powder was prepared by coprecipitation. XRD, XPS and SEM were used in analyzing structure characteristcs. Based on ZnFc2O4 nano powder thick film gas sensors were prepared, and their gas sensitive characteristics were tested and gas sensitive mechanism was given. |
