摘要
通过种子沉积法制备出Fe3O4/Mg(OH)2复合材料并进行XRD、SEM测试分析。探究了氨水的浓度与加入速度、搅拌速度及等因素对磁性复合材料形貌的影响。氨水浓度与注入速度的降低,对氢氧化镁基体形貌的影响是相同的,但要使合成磁性复合材料形貌和四氧化三铁粒子在氢氧化镁中分散性均匀,应控制氨水浓度(ω=2.5%)或加入速度在一个合理的较低值。
Fe3O4/Mg(OH)2 composites was prepared by seed deposition method and analyzed by XRD and SEM.The effects of ammonia concentration and injection rate,stirring speed on the morphology of magnetic composites were investigated.The decrease of ammonia concentration and injection rate led to the formation of flake structures.In order to manipulate the morphology of magnetic composite materials and the dispersion of ferric oxide particles in magnesium hydroxide,the concentration of ammonia(ω=2.5%)or the addition rate should be controlled at a reasonable lower value.
