A New Approach to the Understanding of the Mechanism of Lead Electrodeposition

The Cathodic Polarization Curves in Electrodeposition of Metals

“…[23] with kind permission from Springer) ohmic and diffusion portions in the part of the polarization curve up to the inflection point ( Fig. 1.7b for 0.30 M Pb(NO 3 ) 2 in 2.0 M NaNO 3 ) [12,23].…”

“…The basic characteristic of the full ohmic control is the linear dependence of the current density on the overpotential up to the inflection point ( Fig. 1.7b for 0.45 M Pb(NO 3 ) 2 in 2.0 M NaNO 3 ) [12,22,23]. On the other hand, the polarization curve characterizing the mixed ohmic-diffusion control consists of [12] with permission from Elsevier and Ref.…”

Fundamental aspects of lead electrodeposition processes: Nucleation and growth

“…Rentgensko-difrakciona analiza olovnih taloga je pokazala da bez obzira na tip elektrolita i uslove elektrohemijskog taloženja, u svim gore pokazanim i analiziranim morfološkim formama, kristaliti olova su bili dominantno orijentisani u (111) ravni [17,24,28,29]. Prisustvo kristalita orijentisanih u ostalim ravnima karakterističnih za ovaj tip kristalne rešetke, kao što su (200), (220), (311) i (331) ravan, je bilo primetno manje nego u (111) ravni.…”

“…Za ovaj tip rešetke, odnos brzina rasta kristalnih ravni je sledeći: (110) > (100) > (111) [30]. Ravan (111) pripada sporo rastućim ravnima koja istrajava tokom procesa taloženja, dok brzo rastuće ravni kao što su (200), (220), (311) i (331) nestaju tokom procesa elektrohemijskog taloženja [28,29]. .…”
