The use of metal oxides as materials in ceramic humidity sensor has been widely applied. Compared to other oxides, Mn-Zn Ferrite synthesized from MnO2, ZnO, and Fe2O3 is more superior due to its very high sensitivity to the presence humidity when used as a material for thick film in humidity sensor....

| Summary: | The use of metal oxides as materials in ceramic humidity sensor has been widely applied. Compared to other oxides, Mn-Zn Ferrite synthesized from MnO2, ZnO, and Fe2O3 is more superior due to its very high sensitivity to the presence humidity when used as a material for thick film in humidity sensor. In this research, synthesis of Mn-Zn Ferrite powder was done by varying the composition into 0.75MnO0.25ZnOFe2O3, 0.25MnO0.75ZnOFe2O3, and 0.5MnO0.5ZnOFe2O3. After Mn-Zn powder was acquired, characterizations were carried out. Based on the XRD result, it was identified that Mn-Zn Ferrite phase had formed for each composition. The hysteresis curve showed that the synthesized Mn-Zn Ferrite powder had soft magnetic properties and the SEM characterization showed that size distribution and textures of Mn-Zn Ferrite particles already fulfilled the requirements needed to be applied as humidity sensor. |
