Abstract:
The morphology of crystals precipitated from silver bromide complex solutions in organic solvents has been studied by scanning electron
microscopy. {1 0 0}, {1 1 1}, {1 1 0} and {3 3 1} were the main forms found in these crystals. The crystals could adopt a large variety of shapes
similar to those found in aqueous precipitation. The large size of the crystals allowed a clear observation of the side faces on tabular crystals. The
expected ridge-trough disposition of {1 1 1} faces on the sides was very rarely observed and only as a result of crystal fracturing or re-dissolution.
On the contrary, the sides were formed by a continuous plane from top to bottom forming an acute dihedral angle alternatively with the top and
bottom face in the hexagonal crystals, and, by two planes with an outward inclination meeting at some middle point in the case of triangular crystals.
{1 0 0} faces were also observed on the sides of relatively thick tabular crystals sitting on the acute edges. (C) 1998 Elsevier Science B.V. All rights
