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.

Pure and doped Strontium tartrate tetrahydrate single crystals were grown in silica gel. The growth features of these crystals with variation of parameters like specific gravity of gel, gel PH, acid concentration, concentration of feed solution and gel age were studied in detail.

Cross Linking

Borosulfates are a rapidly expanding class of silicate analogue materials, where the structural diversity is expected to be at least as large as known for silicates. However, borosulfates with cross-linking of the anionic network into two or even three dimensions are still very rare. Herein, we present two new representatives with phyllosilicate analogue topology. Through solvothermal reactions of ZnO and MnCl2∙4H2O with boric acid in oleum (65% SO3), we obtained single-crystals of Mn[B2(SO4)4] (monoclinic, P21/n, Z = 2, a = 8.0435(4), b = 7.9174(4), c = 9.3082(4) Å, β = 110.94(1)°, V = 553.63(5) Å3) and Zn[B2(SO4)4] (monoclinic, P21/n, Z = 2, a = 7.8338(4), b = 8.0967(4), c = 9.0399(4) Å, β = 111.26(1)°, V = 534.36(5) Å3). The crystal structures reveal layer-like anionic networks with alternating vierer- and zwölfer-rings formed exclusively by corner-linked (SO4)- and (BO4)-tetrahedra.

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.
