Abstract

Glycine assisted self-combustion method resulted in fabrication of cobalt-manganese ferrite substituted by zinc ( Zn ) element. The as-synthesized Zn substituted Co-Mn ferrite was subjected to heat treatment at 600?C and 800?C for 2h. Effects of heat treatment on the structural, morphological, surface and magnetic properties of ZnCoMn ferrite were studied. These properties were characterized by using various techniques including TGA-DTGA, FTIR, XRD, SEM, EDX, TEM and VSM. The results showed that the used preparation route led to the formation of nano crystalline Zn0.2Co0.4Mn0.4Fe2O4 particle with cubic spinel type structure. The crystallinity of this ferrite increases as the heat treatment increases. However, the preparation method resulted to the creation of spongy, fluffy, foamy and fragile material with cubic type structure with some agglomerations. Increasing the calcination temperature from 600?C to 800?C, led to a decrease in the surface area (39.4 %) of the as-synthesized ferrite. This treatment causes an increase in the magnetization(40.3%) of this ferrite. The heat treatment that led to various changes in the different properties of the manufactured ferrite was discussed.

热处理对Zn取代Co/Mn铁氧体纳米颗粒性能的影响

甘氨酸辅助自燃法制备了锌取代钴锰铁氧体。将合成的Zn取代Co-Mn铁氧体在600℃下进行热处理。C和800?2h的C。研究了热处理对ZnCoMn铁氧体的组织、形貌、表面和磁性能的影响。采用tg - dtga、FTIR、XRD、SEM、EDX、TEM和VSM等技术对其进行了表征。结果表明:采用该制备方法制备出具有立方尖晶石型结构的纳米晶Zn0.2Co0.4Mn0.4Fe2O4颗粒;该铁氧体的结晶度随着热处理的增加而增加。然而，这种制备方法产生了海绵状、蓬松状、泡沫状、易碎的立方体结构材料，并有一些结块。将煅烧温度从600?C到800?C，导致合成的铁氧体表面积减小(39.4%)。这种处理使铁氧体的磁化强度提高了40.3%。讨论了热处理对制备的铁氧体各种性能的影响。
