Abstract—
An expression for the generalized capillary constant of an equilibrium crystal, taking into account the influence of the gravitational field, is obtained. The height limit for an equilibrium single crystal is determined. It is shown that the equilibrium form of a macrocrystal, oriented randomly in the gravity field, cannot be described by a convex polyhedron. Thermodynamic calculations of the gravity effect on the form of a stationary growing crystal in stirred and immobile homogeneous solutions have been performed. It is shown that gravity barely affects the stationary form of a growing crystal in a thoroughly stirred solution at low temperature; however, growth in an immobile homogeneous solution leads to a significant relative decrease in the crystal height.
