They are uniform and we control their thickness by the number of deposition/dissolution cycles. The film formed during 30 cycles is ultra-thin; the high conductive ITO can be seen through the deposit. At pH 2 (images 11-14 in Fig. ), the precipitates are quite dense and not very branched, and when heated, it cracks. A special precipitate is observed during precipitation from an electrolyte with pH 3.5 (images 19-22 in Fig. ). The sediment is porous and looks like a sponge, but there is a spreading, which can be associated with the presence of hydrolyzed forms in the composition. The precipitates formed by the CA method are shown on images 7-10, 15-18, 23-26 (Fig. ). They have a denser structure and we can see sometimes cracks formed in the film. Pay attention to the sediment formed in the electrolyte with pH 1 by the CA method (images 9,10 in Fig. ). When drying at 90 0 C, dense spherical shapes are formed.
