Effect of Mechanochemical Activation Conditions on the Physicochemical Properties of Zinc Oxide

Abstract

The mechanical activation of zinc oxide with the addition of a surfactant (triethanolamine) in mills of two types — roller-ring vibratory and planetary-centrifugal — is examined. The dependences of the specific surface area on the activation time and content of the surfactant are presented and the effect of the mechanochemical activation on the pore-radius distribution, the dispersity of zinc oxide, and the surface morphology is shown. It is shown that the physicochemical properties of activated zinc oxide make it useful for the production of technical ceramic in the form of carriers for the catalysts and adsorbents used in the desulfurization of gases.
