采用聚合法制备了在交流磁场中具有自加热能力的尖晶石型MgFe 2 O 4铁氧体粉体，研究了其在癌组织热凝固治疗中的应用。采用不同的CA/MN（柠檬酸/金属硝酸盐）条件合成的样品均得到了单相的立方铁氧体结构。当CA/MN=2.0时（ΔT = 168°C），样品的发热能力得到极大提高，但随着CA/MN比的增加，发热性能下降。当CA/MN=2.0时，样品的磁滞损耗值也有所增加，表明聚合法制备的MgFe 2 O 4粉体的发热能力取决于磁滞损耗值。
The spinel type MgFe2O4ferrite powder having self-heating ability in an AC magnetic field was prepared by polymerization method in order to investigated the application for thermal coagulation treatment of cancer tissue. The single phase of cubic ferrite structure was obtained for all sample synthesized with different CA/MN (Citric Acid / Metal Nitrate) conditions. The heat-generation-ability was extremely improved at CA/MN=2.0 sample (ΔT = 168°C), however the heat-generation-property decreased with increase in CA/MN ratio. Hysteresis loss value also increased at CA/MN=2.0 sample, it was suggested that the heat-generation-ability of MgFe2O4powder prepared by polymerization method was depended on hysteresis loss value.
