T. Yoshioka et al., A PREPARATION METHOD OF SECTIONS OF FINE PARTICLES AND CROSS-SECTIONAL TRANSMISSION ELECTRON-MICROSCOPY OF NI POWDER, Journal of Electron Microscopy, 46(4), 1997, pp. 293-301
A preparation method for sections of powder particles has been develop
ed, where the particles are embedded in the Ni(P) foil deposited on a
Ni substrate by electroless plating and then ion-thinned together with
the foil. Ni powder particles, produced by chemical vapour deposition
or liquid-phase reduction, were thinned by this method, and were obse
rved by cross-sectional transmission electron microscopy. The Ni parti
cles often contained subgrains with sharp boundaries such as (111) twi
n boundaries.
