Properties of ZnO in dependence on method of preparation and size distribution in coatings

The problem of environmental protection set strict limits for the use of toxic pigments (e.g., lead, cadmium and other heavy metals). At present, a new generation of pigments called environmental friendly is looked for elimination of these heavy metals. The aim of this work was preparation of different kinds of zinc oxide by various methods, the characterization of these particles and subsequently to pass judgment on their anticorrosion efficiency in coatings.
