Abstract

The present invention provides a method for preparing soft magnetic metal iron porous micro-wires. The present invention adopts divalent iron salt as raw material and anhydrous ethanol, isopropanol and ethylene glycol as solvent to prepare soft magnetic wire by solvothermal reduction method. Metal iron porous microwires. The method obtains iron micro-wires with different lengths, different diameters and different pore sizes by controlling factors such as reaction temperature, reaction time, reactant concentration, ligand and solvent types. The method for synthesizing the soft magnetic metal iron porous micrometer wire in one step requires simple equipment, simple preparation process and low production cost. The invention provides a new method for preparing soft magnetic metal iron porous micro-wires.

Description

technical field

[0001] The invention relates to a preparation method of a soft magnetic metal material, in particular to a preparation method of a soft magnetic metal iron porous micron wire, and belongs to the field of magnetic material preparation. Background technique

[0002] In recent years, magnetic materials have been widely used in electromagnetic wave absorption, sensitive components, magnetic storage, catalysts, medicine and biological functions due to their unique magnetic properties. As a special functional material for magnetoelectric conversion, soft magnetic material has high saturation magnetization and low coercivity, and is an important component for constructing new electromagnetic functional materials. The microstructure of soft magnetic materials determines its macroscopic properties. Therefore, many researchers strive to maintain a high magnetic flux by designing its structure, and control its coercive force and hysteresis loss to improve its macroscop...
