Nano-meter micro-porous Ni_xZn_((1-x))Fe_2O_4 (x=0,0.5) ferrites were obtained by hydrothermal method. Triethylamine was used as template by differential thermal analysis (DTA). The results of adsorption experiment show that the powder has micro-porous structure. The crystal structure of the powder was studied by X-ray Diffraction (XRD), and the results show that the powder is of spinel structure. The morphology of Ni_xZn_((1-x))Fe_2O_4 (x=0, 0.5) ferrite was studied by TEM, and the results show that Ni_(0.5)Zn_(0.5)Fe_2O_4 and ZnFe_2O_4 ferrite is well-crystal, well-degree of dispersion with little conglomeration because of weak magnetism. The size of the powder is below 50 nm.
