“…Crystals of small size have been grown as well in open tube systems, either by oxidation of ZnI 2 [156], ZnS, ZnSe [157], ZnBr 2 [158], and Zn [159][160][161] or by hydrolysis of ZnF 2 [162], ZnCl 2 [163,164], or ZnI 2 [165]. The oxidation or hydrolysis character of the reaction can depend on the temperature range used for a same source.…”

Crystallization of ZnO was accomplished by different methods in order to study several problems of structure and growth kinetics. Zincite was grown by react5on of ZnF with air, by crystallization from a molten salt solution (system ZnOPbF,), procedures already known, further on by sublimation and by chemical transport reaction.Crystals developed equilibrium forms characteristic for wurtzite type structure ; that are the forms { OOOl}, { 1610) and { 1071) with bipolar developement. While this combination is stable under different physico-chemical conditions the crystal habit varies in a wide range. Whiskers were found that had grown by sublimation as well as linear (by chemical transport reaction od ZnF,) and planar types crystals, the latter having been grown from molten salt solvents. The described variations of morphology may be well understood on the basis of growth mechanisms that are to be expected and observed for wurtzite type crystals.X-ray analysis confirms the ZH-structure (wurtzite) for all the crystals grown by several methods independent from variations in growth conditions and habit. Polytypes and the cubic modification could not be observed. The facts dealt with may be explained in terms of ionic portions in valence.
