When present in ethylene diamine tartrate (EDT) solutions in small concentration boric acid produces many crystallographic phenomena associated with specific adsorption on crystal faces; especially habit modification and growth inhibition. These effects are typical of those given, incidentally, by "growth improvers", and it is concluded that boric acid would be a logical choice for intensive testing as a flaw suppressor in the solutions from which large single crystals of EDT are grown.

Controlled Conditions

Single crystals of ethylene diamine tartrate were grown under controlled conditions and the growth rate of the faces measured directly in the solution at short intervals by means of a travelling microscope. For the [Formula: see text] pair of faces, the fastest growing form, steady growth at constant supersaturation was interrupted by occasional short periods of more rapid growth. Rejecting these erratic "spurts", reasonably reproducible values could be obtained, and the dependence upon supersaturation plotted. The equivalent faces at the opposite end of the polar axis of the crystal grew, at low supersaturation, with erratic starts and stops, so that reproducible growth-rate values could not be obtained. The results are discussed in relation to existing crystal growth theories.

Good Agreement

Measured growth and dissolution rates of single crystals and tablets were used to calculate the overall linear rates of growth and dissolution of CuSO4.5 H2O crystals. The growth rate for the tablet is by 20% higher than that calculated for the single crystal. It has been concluded that this difference is due to a preferred orientation of crystal faces on the tablet surface. Calculated diffusion coefficients and thicknesses of the diffusion and hydrodynamic layers in the vicinity of the growing or dissolving crystal are in good agreement with published values.
