Zinc oxide was obtained by precipitation from solutions of KOH and Zn(CH3COO)2. The effect of excessive presence of one of the reagents and temperature on the physico-chemical properties, structure and size of zinc oxide particles was analysed. The main aim of the study was to establish the optimum conditions of precipitation that would ensure getting the uniform particles of zinc oxide of the minimum diameter. The zinc oxide obtained had particles of nano- and micrometric size. The adsorption/desorption isotherms indicated the mesoporous character of the product. The wettability of ZnO obtained was determined first of all by the morphology and particle size.
