Abstract

By using FeSO₄·7H₂O, NiSO₄·6H₂O and ZnSO₄·7H₂O as raw materials, with a coprecipitation method, the basic carbonate precursor containing very fine crystalline grain is first synthesized and then nanocrystalline (Ni,Zn)Fe₂O₄ composite particles followed by sintering for one hour can be obtained. The microstructure was measured by using XRD and TEM. And then, the infrared absorption and gas-sensitization of the samples have been investigated. The results show that the diameter of the nano-particles is about 50nm at 800℃.
