| Abstract
| - Adherent BaSO4 coatings have been electrochemically deposited on anode substrates fromaqueous solution for the first time by electrogeneration of acid. At low current densities,thick, nearly continuous coatings comprising unoriented crystallites are obtained. At highercurrent densities, the coatings are not as continuous but the crystallites are oriented. Atshort deposition times and under high current densities, the crystallites are oriented withthe a axis perpendicular to the substrate. At long deposition times, the orientation switchesto the c axis. Electroless deposition under similar conditions yields crystallites that areneither oriented nor facetted.
