A method suitable for prototyping unconventional times of scanning electron microscopy

The present application provides a method for manufacturing a sample suitable for SEM unconventional times, comprising: A sample was cut into a predetermined shape; coarse grinding of the sample surface; alumina mortar and / or alumina powder fine grinding of the sample surface; alumina suspensions, or containing aluminum oxide and diamond-mixed suspension of the sample to a rough polishing; after washing the sample, the sample was stuck on a preset glass; after the sample cut out grinding, to reduce the thickness of the sample to 10-15 [mu]; suspension of alumina, or alumina-containing suspension was mixed with the diamond sample the rough polishing; oxidation using aluminum suspension or the silica suspension sample fine polishing; ion sputter deposition using a carbon layer on the sample surface. This application may be of different minerals porosity and permeability of the size of the contribution.
