Title:
SILVER-BASED METAL POWDER AND METHOD FOR MANUFACTURING SILVER-BASED METAL POWDER
Document Type and Number:
WIPO Patent Application WO/2024/089840
Kind Code:
A1
Abstract:
[Problem] To provide a silver-based metal powder with which stable sintering/burning is possible even in an atmosphere with a low temperature and/or high dew point and which, by having less variation in the strength and dimensions of the sintered bodies, can be used preferably as a raw material powder for powder metallurgy and/or a raw material powder for conductive paste material. [Solution] A silver-based metal powder wherein: the standard free energy of formation of an oxide contained in the silver-based metal powder in a temperature range at or below 600°C is equal to or lower than the standard free energy of formation of silicon dioxide in said temperature range; and the total content of an impurity element having a mixing enthalpy with silver of equal to or lower than aluminum is equal to or lower than 500 ppm.
