Abstract
A new and simple method for the preparation of uniform zinc oxide colloidal particles of different morphologies by controlled double-jet precipitation is described. Scanning electron microscopy and X-ray diffraction data indicate that the solids generated under different conditions have identical crystallite structures, although they are internally composite. The growths of the subunits and of the particles themselves follow different patterns. Particles formed in the presence of a surfactant (sodium dodecyl sulfate) exhibit essentially the same overall characteristics, but the particles are microporous.Keywords
