New developments in the preparation of nano barium ferrite

The technology research on nano-barium ferrite preparation progress was reviewed.Nano-barium had broad application prospect for its excellent ferrite magnetic and microwave absorbing properties.In recent years many nano-barium ferrite preparation process,sol-gel method were proposed for the preparation of nano-barium ferrite powder and film because of its unique superiority in the control of product composition and uniformity,but some new technology mechanism needs further study.The analysis shows that the nano-barium ferrite preparation needs to be further improved.The nano-barium ferrite and conductive polymer composites,nano-barium ferrite doping,nano barium ferrite doped and conductive polymer composites shall be further investigated in future.
