“…The obtained values between 18.4 -88 mA cm -2 were in the excellent agreement with those proposed by Bockris et al [40] (j 0 between 8 and 370 mA cm -2 ) The obtained values are compared with those obtained by chronopotentiometric method following procedure given in Ref. [10]. In chronopotentiometry, the overpotential dependence on time is given by Eq.…”

“…The shape of powder particles depends on both the conditions of electrolysis, such as the current density or overpotential, the type and composition of electrolyte, temperature, the type of working electrode, regime of electrolysis, etc., and the nature of metals [6]. Although powder particles are the most often dendritic shape, they can also be in the form of flakes, fibrous, spongy, wires at sub-micrometer or nanometer scale, cauliflower-like, as well as in the many other irregular forms [4][5][6][7][8][9][10][11][12][13][14][15][16]. Various forms of dendrites are formed by electrolysis, and the shape of dendritic particles is primarily determined by the type of metals [4,6,9,[11][12][13][14].…”

Silver powders chemically synthesized by reduction with hydrazine and those produced by electrolysis from the basic (nitrate) and complex (ammonium) electrolytes were examined by X-ray diffraction (XRD) and scanning electron microscopic (SEM) analysis of the produced particles. Morphologies of the obtained particles were very different at the macro level. The needle-like dendrites, as well as the mixture of irregular and regular crystals, were formed from the nitrate electrolyte, while the highly-branched pine-like dendrites with clearly noticeable spherical grains were formed from the ammonium electrolyte. The agglomerates of spherical grains were formed by reduction with hydrazine. In the particles obtained from the nitrate electrolyte, Ag crystallites were strongly oriented in the (111) plane. Although morphologies of Ag particles were very different at the macro level, the similarity at the micro level was observed between chemically-synthesized particles and those obtained by electrolysis from the ammonium electrolyte. Both types of particles were constructed from the spherical grains. This similarity at the micro level was accompanied by the similar XRD patterns, which were very close to the Ag standard with a random orientation of Ag crystallites. For the first time, morphologies of powder particles were correlated with their crystal structure.

“…These compounds form enough strong complexes with Ag(I) ions to cause a decrease in j 0 for Ag and its transfer from the group of the normal metals into the group of the intermediate metals. The 3D pine-like dendrites of Cu with well-defined corncob-like branches represent the typical shape of Cu dendrites obtained by electrolysis processes [45][46][47][48].…”

In this review paper, morphologies of metal powders produced by the constant (potentiostatic and galvanostatic) regimes of electrolysis from aqueous electrolytes are correlated with their crystal structure at the semiquantitative level. The main parameters affecting the shape of powder particles are the exchange current density (rate of electrochemical process) and overpotential for hydrogen evolution reaction. Depending on them, various shapes of dendrites (the needles, the two-dimensional (2D) fern-like, and the three-dimensional (3D) pine-like dendrites), and the particles formed under vigorous hydrogen evolution (cauliflower-like and spongy-like particles) are produced by these regimes of electrolysis. By decreasing the exchange current density value, the crystal structure of the powder particles is changed from the strong (111) preferred orientation obtained for the needle-like (silver) and the 2D (lead) dendrites to the randomly orientated crystallites in particles with the spherical morphology (the 3D dendrites and the cauliflower-like and the spongy-like particles). The formation of metal powders by molten salt electrolysis and by electrolysis in deep eutectic solvents (DESs) and the crystallographic aspects of dendritic growth are also mentioned in this review.
