PROCEDE DE FABRICATION D'UNE POUDRE D'OXYDE DE ZINC DOPE, ET POUDRE OBTENUE.

摘要

The method consists in producing zinc oxide by precipitation of a precursor comprised of a mixed monophase zinc carbonate and of dopes wherein atoms of bismuth and other dopes are substituted for zinc atoms; the mixed carbonate is then subjected to decomposition heat treatment resulting in a mixed oxide of zinc, bismuth and other dopes. The method can be used to produce powders of doped zinc oxide which are homogeneous with respect to all elements present and having a controllable morphology.
