Abstract: Ferrite， a prevalent magnetic loss absorbing material， underscores the significance of its preparation method in determining both its structure and absorbing properties. Traditionally， ferrites are predominantly synthesized through solvothermal or hydrothermal methods， which entail substantial energy consumption and exhibit limited compatibility with other materials. Octahedral Fe3O4 is successfully synthesized via a low-temperature （50 ℃） co-precipitation process， utilizing ferrous chloride as the iron source. The oxidation reaction is meticulously controlled using potassium nitrate. Furthermore， the absorption effectiveness of the resultant product under various reaction conditions is thoroughly examined. Notably， the composite material formed by combining NiCo2O4 and Fe3O4 exhibits superior absorbing properties. This low-temperature approach not only mitigates the demands on equipment and energy consumption but also enhances material compatibility， thereby significantly expanding the application scope of ferrite materials.
