ABSTRACT:
A method for preparing electrically-conductive zinc oxide is herein disclosed, which comprises the steps of preparing a vapor mixture comprising zinc vapor and vapor of at least one member selected from the group consisting of dopant-forming metal compounds having boiling points of not more than that of zinc and free of oxygen atom in a predetermined mixing rate ranging from 0.005 to 5 parts by weight of the dopant-forming metal, as expressed in terms of the oxide thereof, per 100 parts by weight of zinc, as expressed in terms of zinc oxide; then oxidizing the vapor mixture with an oxidizing gas.
