Zinc hydroxide film with dopant of aluminum have been obtained by chemical deposition from aqueous solutions. The conditions of the co-deposition of zinc and aluminum hydroxides, using methods of calculation conditions of ionic equilibrium in solution was identified. The phase composition and morphology of the resulting products was studied by X-ray analysis and scanning electron microscopy. In strongly alkaline region there was a formation of zinc oxide films. In the composition of the coatings deposited from solutions having a pH = 10-12, revealed the presence of phase Zn5(OH)8(NO3)2 ∙ 2H2O. Addition of 2-3 atm. % aluminum salt in the initial zinc salt solution led to a change of the morphology and phase composition of the film, expressed in two-layered formation of an inhomogeneous coating containing inclusion particles having a size of 5 to 10 microns with a hexagonal facet explicit. The presence of a complex phase hydroxycarbonate zinc - aluminum was established.
