2.3.3. Scanning Electron Microscopy Experiment

The internal microstructure of the CGFB samples was examined using the Apreo S Hivac high-resolution SEM. The samples were soaked in alcohol and dried. After the surface of the samples was blown clean using an ear-washing ball, they were pasted on the sample table using a conductive adhesive. The internal structure of the samples was observed after the surface was sprayed with gold.
