摘要
采用液相共沉淀法制备纳米级Fe3O4颗粒,并利用芷交设计法对制备纳米级Fe3O4颗粒的影响因素如Fe3+/Fe2+的物质的量比、制备Fe3O4的晶化温度和晶化时间等进行实验设计,利用Zetasizer粒径分布仪对所制备纳米粉的颗粒大小进行表征,据此找出最佳实验条件为Fe3O4的晶化温度为90℃,Fe3+/Fe2+的物质的量比为1:2和制备Fe3O4的晶化时间为30min,此时制得的纳米粉体平均粒径可达15nm;并利用XRD、HRTEM对所制备纳米粉进行结构表征.
The preparation of Fe3O4 nanoparticle with liquid- phase coprecipitation was introduces, making full use of processing conditions, experiment design to the influence factors such as atomic ratio of Fe / Fe2+, crystal temperature of Fe3O4nanoparticle, crystal time of Fe3O4 nanoparticle. The size distribution of nanoparticle was charactered by Zetasizer. The optimization condition were achieved that atomic ratio of Fe3+/ Fe2+ is 2:1, crystal temperature of Fe3O4 nanoparticle is 70℃, crystal time of Fe3O4 nano...
