Method of preparing aluminum-containing alloy powder and application thereof

Abstract

The present disclosure relates to a method of preparing an aluminum-containing alloy powder and an application thereof. The preparation method includes: by using the characteristic that a solidification structure of an initial alloy includes a matrix phase and a dispersed particle phase, the matrix phase is removed by reaction with an acid solution, so as to separate out the dispersed particle phase and obtain an aluminum-containing alloy powder. The preparation method is simple in process and can prepare different morphologies of aluminum-containing alloy powders of nano-level, sub-micron-level, micron-level and millimeter-level, which can be applied to the fields such as photo-electronic devices, wave absorbing materials, catalysts, 3D metal printing, metal injection molding and corrosion-resistant coating.
