Structural Features and Magnetic Properties of Bentonite–Iron Oxide Composite Materials
A mixed magnetite–maghemite solid solution and a bentonite–iron oxide composite material are synthesized via chemical coprecipitation. It is found that the bentonite–iron oxides composite is characterized by considerably weaker residual magnetization and stronger coercive force than Fe3O4/γ-Fe2O3 powder. X-ray diffraction and Mössbauer spectroscopy data show that bentonite influenced structural features of the magnetite–maghemite in the composite.
