| 中文摘要: |
| 采用化学包覆法,以氨水为沉淀剂,在碱性体系中制备了Fe(OH)3包覆T-ZnOw复合粉体,在600℃下通氢气还原获得了Fe/ T-ZnOw包覆复合粉体。用XRD,SEM和EDX对粉体进行表征,结果表明:复合粉体存在金属铁相和T-ZnOw相,T-ZnOw四针保持完整,表面包覆完整,铁颗粒为球形,颗粒细小均匀,并T-ZnOw表层外有部分散落铁颗粒,颗粒粒径约为3μm。用VSM分析测定粉体的磁饱和强度和矫顽力,分别为32.10 emu/g和140.5 Oe。 |
| 英文摘要: |
| 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. |
