摘      要：Silver dendritic nanonstructures obtained by the potentiostatic electrolysis from different electrolytes at different overpotentials were characterized by the scanning electron microscopy(SEM)technique and X-ray diffraction analysis of the produced *** needle-like and fern-like dendrites were formed from the nitrate electrolyte at overpotentials inside and outside plateaus of the limiting diffusion current density,*** three-dimensional pine-like dendrites constructed from approximately spherical grains were formed from the ammonium electrolyte at overpotentials both inside and outside plateaus of the limiting diffusion current *** morphology of silver dendrites was correlated with their crystal structure at the semi quantiative *** change of crystal orientation from the strong(111)preferred orientation for the needle-like dendrites to almost randomly orientied spherical grains in the pine-like dendrites obtained at the overpotential outside the plateau of the limiting diffusion current density was *** trend in change of crystal orientation and morphology of Ag nanostructures was accompanied by considerable increase of the specific surface area(SSA)of the produced *** average crystallite sizes were in the range of 38-50 nm,proving nanostructural character of the formed Ag particles.
