摘　　要：本实验通过改良的多元醇法制备并表征四氧化三铁磁性纳米颗粒。对方法改良前后的生成物做了对比。结果显示,改良前后制备得到的产物均为反尖晶石结构,结晶度高;但改良后的产物颗粒更加均匀,粒径增大,约为12～15 nm,几乎无团聚。This experiment by modified polyols preparation and characterization of the ferromagnetic oxide nanoparticles. For ways to improve products made before and after contrast. Results show that the improved preparation before and after the products are the spinel structure,high crystallinity. But the product of the modified particles is more uniform,particle size increase,about 12～15 nm,almost no reunion.
