Abstract: The roller vibration mill was used to manufacture zinc of 40 nm in diameter in dry mode and at room temperature and used co-precipitatcd method to prepare Fe3O4 of 10nm in diameter. Consequently, the hydrolyzing system ofZn nano-particles and FeO nano-particles was used to prepare ZnFeX>4 nano-particles. When the temperature got to 300 % and 320 X., the peaks of ZnFeXX were obviously appearance in XRD pattern. Both of the samples were all around 15 nm in diameter according to TEM, and ED pat・ tern. HRTEM were also used to detected the two sample
