Method for manufacturing aluminum base material

Abstract

A manufacturing method can obtain Al-based particles. A particle-dispersed molten salt (an example of an Al base material), in which Al-based particles (liquid phase) are dispersed in molten salt, can be obtained by bringing Al-based foil into contact with molten salt. Through particle-dispersed molten salt, for example, Al-based powder (an example of Al base material) composed of Al-based particles (solid phase) can be efficiently or easily obtained. By classifying Al-based particle groups, Al-based powder with a desired particle size distribution can be obtained. The Al-based foil has a thickness of, for example, at most 0.5 mm, and even 0.1 mm. The Al-based foil is supplied to molten salt in the form of shredded foil pieces. This allows Al-based powder to be obtained with a particle size distribution including fine particles. It is preferred to use, for example, a mixed salt containing NaCl and KCl as molten salt.
