Abstract

Adherent $BaSO_4$ coatings have been electrochemically deposited on anode substrates from aqueous solution for the first time by electrogeneration of acid. At low current densities, thick, nearly continuous coatings comprising unoriented crystallites are obtained. At higher current densities, the coatings are not as continuous but the crystallites are oriented. At short deposition times and under high current densities, the crystallites are oriented with the a axis perpendicular to the substrate. At long deposition times, the orientation switches to the c axis. Electroless deposition under similar conditions yields crystallites that are neither oriented nor facetted.
