Title:
EMBEDDING AND FIXATION COMPOSITION FOR IMPROVING VISIBILITY IN OBSERVATION USING ELECTRON MICROSCOPE OR THE LIKE, AND OBSERVATION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/223521
Kind Code:
A1
Abstract:
Provided are: an embedding and fixation composition that enables clear visualization of a microstructure of a solid material formed of a light element such as graphite and boron nitride and thereby improving the visibility thereof, in observation using an electron microscope or the like; and an observation method with an electron microscope or the like using the embedding and fixation composition. According to the present invention, a water-soluble polymer such as polyvinyl alcohol and a water-soluble heavy metal salt such as phosphotungstic acid are dissolved in water to obtain a liquid composition. A solid material is impregnated with the liquid composition, which is then solidified, to have a microstructure embedded and fixed. Then, the microstructure is observed using an electron microscope or the like.
