METHOD FOR PREPARING SAMPLE FOR ELECTRON MICROSCOPE, AND METHOD FOR ANALYZING REACTION PRODUCT METAL-CONTAINING PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a sample endurable to a pretreatment at the time of observation for metal salt-containing particles formed in a reaction product by an electron microscope; and a method for enabling analysis including observation for the sample by the electron microscope.SOLUTION: When reaction product metal-containing particles are coated with a resin, a thickness of coating in a portion that is an observation object in the reaction product metal-containing particles is set at 20 μm or less.SELECTED DRAWING: Figure 2
