Title:
METHOD FOR MANUFACTURING ALUMINUM SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2024/053275
Kind Code:
A1
Abstract:
Provided is a manufacturing method by which Al-based particles can be efficiently or easily obtained. According to the present invention, a particle-dispersed molten salt (an example of an Al substrate), in which Al-based particles (liquid phase) are dispersed in a molten salt, can be obtained by bringing an Al-based foil into contact with a molten salt. Through the particle-dispersed molten salt, for example, Al-based powder (an example of the Al substrate) comprising Al-based particles (solid phase) can be efficiently or easily obtained. By sorting the Al-based particle group, an Al-based powder with a desired particle size distribution may be obtained. The Al-based foil has a thickness of, for example, at most 0.5 mm, and even 0.1 mm. Preferably, the Al-based foil is supplied to a molten salt in the form of chopped foil pieces. Accordingly, it is possible to easily obtain Al-based powder having a particle size distribution including fine particles. For example, it is preferable that a mixed salt containing NaCl and KCl be used as the molten salt.
