Abstract
A method is provided for the high yield production of white, electrically conductive zinc oxide which comprises the simultaneous addition to a reactor of (1) an aqueous solution containing a water-soluble zinc compound and at least one water-soluble compound of a metal selected from the group consisting of tin, aluminum, gallium and indium, and (2) an aqueous alkaline solution, while maintaining the resulting neutralization reaction solution at a pH from 6 to 12.5 to obtain coprecipitates, and then calcining the coprecipitates in a reducing atmosphere to obtain said conductive zinc oxide.
