| Abstract: |
| T-ZnOw coated Fe(OH)3composite powders were prepared in the basic system by the chemical coating method using ammonia as the precipitating agent. Fe/ T-ZnOw composite powder was obtained through hydrogen reduction at 600℃ . The powder was characterized by XRD,SEM and EDX. The results show that there are metal iron phase and T-ZnOw phase in the composite powder. The tetrapod of T-ZnOw wasintact and coated fully by iron particles.Some iron particles, shperical particle about 3μm, were scattered outside the surface of T-ZnOw. Saturation magnetization and coercivity of the composite powder were measured by the VSM, respectively 32.10 emu/g and 140.5 Oe. |
