摘要：
In this paper, we report on the gas sensing properties of Ni0.6Zn0.4Fe2O4 nanoparticles. The samples were synthesized by the microwave method. The synthesized nanoparticles were characterized by X-Ray diffraction, which confirmed the formation of a cubic spinel structure without any detectable impurity phases. The results showed that the average crystallite size was similar to 25 nm. These results were further confirmed by scanning electron microscopy images. The gas sensing properties of the samples were investigated in the presence of acetone and methanol gases. The Ni-Zn ferrite indicated a good response toward the acetone gas compared to the methanol gas, and the best operating temperature for both gases was 250 degrees C.
