Document Type and Number:
WIPO Patent Application WO/2019/188149
Kind Code:
A1
Abstract:
Provided is a method with which it is possible to efficiently manufacture a metal powder having a narrow grain size distribution. This method includes an airflow classification step for performing airflow classification at a classification temperature of 35°C or less on a metal powder to which an alcohol is bonded. The classification pressure may be 0.2 MPa or higher, and the alcohol may have a steam pressure at 20°C of 18.7 hPa or higher. The alcohol-bonded metal powder may include an alcohol having a saturated adsorption amount of 40% or higher. The number-average particle diameter of the metal powder may be 200 nm or less.
