Method of determining particle size distribution of fine particles contained in metallic material

A method comprising: a step in which fine particles contained in a metallic material to be examined are isolated by extraction with a solution using a means of extraction for fine-particle isolation; a step in which the fine particles isolated by extraction are dispersed in a solvent to prepare a di...

Summary:A method comprising: a step in which fine particles contained in a metallic material to be examined are isolated by extraction with a solution using a means of extraction for fine-particle isolation; a step in which the fine particles isolated by extraction are dispersed in a solvent to prepare a dispersion and the dispersion is separated into fine-particle dispersions having respective size ranges with a field-flow fractionation device; and a step in which the fine-particle dispersions having respective size ranges are irradiated with a laser light to determine the absolute value of the size of the fine particles of each dispersion from the angle dependence of the resultant reflected-light intensity, and the number density of the fine particles is determined from the reflected-light intensity.
