Method for producing electrically conductive zinc oxide

摘要

A method for producing electrically conductive zinc oxide comprising calcining zinc oxide under an ambient atmosphere in a vessel at a temperature from about 800 DEG to about 1100 DEG C. in a mixture thereof with aluminum oxide or a precursor thereof convertible into the oxide under the conditions of treatment in an amount of about 0.05 to about 5 moles based on aluminum atom therein in relation to 100 moles of zinc oxide in the presence of solid carbon. A further improvement in the method comprises mixing zinc oxide with aluminum oxide powder of not more than about 20 millimicrons in average particle size in the dry form to provide a feed mixture, and calcining the mixture, to provide a highly conductive form of zinc oxide.
