SEM Micrograph of Tungsten Powder
SEM is shorted from Scanning Electron Microscope, and its picture is taken from enlarged image of SEM. When under SEM, the object can be 20multipled, or even 200,000 multipled, or even larger. The effect of this multiple is obvious, tungsten under SEM has been three-dimentional, clear, and visual sense. Tungsten powder SEM microgragh is like not very round ball, one by one, but separate some. When enlarge more, the gap between the molecules would be bigger.
