Abstract
The present application provides a method for manufacturing a metal foam. The present application can provide a method for manufacturing a metal foam, which is capable of forming a metal foam comprising uniformly formed pores and having excellent mechanical properties as well as the desired porosity, and a metal foam having the above characteristics. In addition, the present application can provide a method capable of forming a metal foam in which the above-mentioned physical properties are ensured, while being in the form of a thin film or sheet, within a fast process time, and such a metal foam.
Claims11
A method for manufacturing a metal foam comprising:
- preparing a structure using a slurry,
- applying an electromagnetic field to the structure,
- wherein the slurry consists of a metal component, an organic binder, and optionally solvent and/or binder,
- wherein the metal component comprises a conductive metal having a relative magnetic permeability of 90 or more,
- wherein the metal component comprises, on the basis of weight, 30% by weight or more of the conductive metal, and
- wherein the metal component to which the electromagnetic field is applied is in the form of powder.
