A method for collecting inclusions and / or precipitates in a metal sample, a method for analyzing inclusions and / or precipitates in a metal sample, and an electrolytic solution.

摘要

To provide a method of collecting and analyzing chemically unstable inclusions and/or deposits in a metal sample without dissolving them, and an electrolytic solution capable of collecting chemically unstable inclusions and/or deposits in metal samples without dissolving.SOLUTION: The collection method of inclusions and/or deposits in a metal sample includes: an electrolysis process of electrolyzing a metal sample in an electrolytic solution; and a collection process in which inclusions and/or deposits adhering to the rest of the metal sample after the electrolysis process are separated, filtered, and collected. In the collection method of inclusions and/or deposits, the electrolyte contains a compound that includes the metal elements constituting the inclusions and/or deposits to be collected.SELECTED DRAWING: None
