The orientations of twinned crystals, obtained by the electrocrystallization of silver, have been investigated for their dependence on overvoltage, using an improved potentiostatic pulse technique. The overvoltage range, where a definite preferred orientation axis appears, fully coincide with the range within which normal crystal display analogous orientation axes. This confirms theoretical calculations, and proves that twinning takes place at a later stage of crystal growth, not being associated with the orientation of the crystallites. Complex twinned-crystal forms, with a “five-fold” symmetry, have been obtained in various orientations. Their formation is explained by a repeated twinning process.
