The wettability of different faces of a number of single crystals (thymol, diphenylamine, dibenzyl, salol, benxophenone, sodium thiosulphate, germanium) by their own melt in the course of their growth was studied using various methods (bubble method, sessile drop method, by the melt meniscus shape). The wettability of the crystals by the own melt is incomplete, the wetting angle differs from zero and is dissimilar for different faces (wettability anisotropy). The highest values of the wetting angles are displayed by the faces having the greatest reticular density. For thynol crystals, the kinetics of face growth has been studied simultaneously with investigating the wettability. The gtowth of close-packed faces featuring the largest wetting angles has been found to be governed by a tangential mechanism. The process of melting of different faces of the above single crystals has been studied by means of microfilming (including that in vacuum at a high temperature). It has been ascertained that the crystal-melt transition at the closest-packed faces proceeds by layers. The liquid phase resulting from layer destruction forms droplets wetting the face with a wetting angle to that in crystal growth. The observed melting mechanism has been termed a ”droplayered” one.
