“…The crystals with well-defined (111) planes as those observed during electrocrystallization of lead [29] can be easily identified among the powder particles obtained from the nitrate electrolyte (Figure 2d,e). The powder particles obtained from this electrolyte showed the strong (111) preferred orientation.…”

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.

“…Većina od ovih granula je sa dobro definisanim kristalnim ravnima i mogu se označiti kao (poli)čestice. Ravni dvojnikovanja se lako uočavaju u većini od ovih čestica [22]. Ove forme granula se formiraju u početnim stupnjevima taloženja na svim prenapetostima i iz svih tipova elektrolita.…”

“…Ove forme granula se formiraju u početnim stupnjevima taloženja na svim prenapetostima i iz svih tipova elektrolita. Tokom taloženja iz razblaženih elektrolita i na nižim prenapetostima, njihov oblik opstaje duže vreme, dok pri taloženju iz koncentrovanih elektrolita i na višim prenapetostima, rast većine od njih je jako brzo zaustavljen [22]. …”

“…7b-b ). According to references [13,15], the controllable parameters enables electrodeposition technique to be a versatile and facile method to fabricate microstructure with novel architectures. The morphologies generally include cubic, octahedral, or truncated versions of these shapes and anisotropic ones such as dendrites, wires, whiskers, fibers, rods, stripes, and so on [43,44].…”

“…The advantages of this way as compared with others are low capital investment and costs, as well as uniform pore size and high porosity of products [3,4]. The electrolytes for lead electroplating are usually acidic such as hydrofluoride [1], pyrophosphate [10], fluorborate [11], fluorosilicate [12], bromide [13], iodide [13], nitrate [14,15], acetate [16] chloride [17], etc. Besides, alkaline solutions are also widely used in lead electrodeposition process [18,19].…”
