✦ Synopsis

Epitaxial growths of zinc electrodeposits deposited on copper single crystal faces have been observed when deposited from highly purified zinc sulphate and ammonium sulphate bath at eds between 2 and 20 mA/cm' . At all cds on the (I11) face hexagonal pyramids are observed, on the (100) face layers appear and on the (110) face a ridge type of deposit is found . The presence of benzaldehyde in small quantities affects the growth habits of zinc and cathodic polarization . An attempt is made to explain the mechanism of the deposition process from the overpotential/ed relationship . The changes in the growth habits of zinc are attributed to adsorption of benzaldehyde on the substrate.
