The conditions and mechanisms of the growth of hollow crystals, dendrite structures, and whiskers of zinc oxide during the annealing of pressed zinc oxide-carbon mixtures were studied. The growth of hollow structures is due to the interaction of reagents in pressed tablets, which is accompanied by the formation of a gas-impermeable external ZnO shell and the transport of Zn vapor and CO[sub 2] along the growing tube. Orientation of the hollow crystals is determined by the direction of Zn vapor transport. The process was modeled by the Zn vapor emission from a Knudsen effusion cell. [ABSTRACT FROM AUTHOR] |
