Description

Technical field [0001] The invention involves the field of electromagnetic absorption materials technology, which is specifically for preparation methods for a FECO alloy covering foam nickel -absorbing material. Background technique [0002] As a kind of bubble nickel, the base materials with stable chemical properties are widely used in many fields such as energy, catalytic and sensors. The introduction of FECO semiconductor materials has a significant performance of foam nickel materials. Common Feco alloy composite materials The preparation methods are mainly mechanical mixed legal, chemical precipitation method, chemical gas deposition method (CVD), and solvent thermal method. It is difficult to mix and uniformly mixed mechanical mixing, and it is difficult to prepare nano composite materials with complicated components. ; Although the chemical precipitation method is simple, it is prone to reunion, which directly affects the appearance and performance of the material; the c...
