摘要 以硝酸锰、硝酸锌、硝酸铁为原料,以柠檬酸为凝胶剂,采用溶胶-凝胶自蔓延燃烧法合成了Mn-Zn铁氧体粉体。借助XRD、SEM和FTIR等方法对所制备产物的磁性能和结构进行分析和表征,研究了溶胶pH值和退火温度对产物的影响。确定出溶胶的pH值为7、退火温度500℃时为最适宜的合成条件,从而制备出粒径尺寸均一、单相、形貌较好的锰锌铁氧体粉体。 Mn-Zn ferrite powders were synthesized by means of sol-gel auto-combustion, using citric acid as gel and Mn, Zn and Fe nitrates as raw materials. Magnetic properties and mierostructures of the ferrite powders were analyzed and characterized by XRD, SEM and FTIR, and the influence of sol pH value and annealing temperature on the magnetic properties and structure of products were researched. As a result, the proper synthetic condition was determined with gel pH value of 7 and annealing temperature of 500＂C. Under the proper synthetic condition fine Mn-Zn ferrite powders with uniform particle size, single phase and good morphology were successfully synthesized.
