Method of Manufacturing Zinc Oxide Fine Powder Utilizing Exothermic Heat of Synthesis Reaction

摘要

The present invention relates to a method for producing high purity zinc oxide (ZnO) fine powder. More specifically, the present invention relates to a method for producing zinc oxide fine powder by reducing or evaporating a raw material mixed with zinc oxide and zinc in a rotary furnace to generate zinc gas and oxidize it again.;According to the zinc oxide production method of the present invention, the equipment required for the production of zinc oxide fine powder is simplified by simultaneously performing reduction of zinc oxide and / or evaporation of zinc and oxidation of zinc gas produced thereby in a single reactor. In addition, it is possible to reduce the zinc oxide production cost by improving the thermal efficiency of the entire process by reusing the heat of reaction generated in the oxidation reaction of zinc gas to the reduction of zinc oxide and evaporation of zinc.
