ABSTRACT:
A method for crystallizing substances, which are dissolved in a liquid at zero-gravity. In order to limit the extent of lattice defects occurring in the crystallized monocrystals as much as possible, it is provided, that the liquid during the crystallization is held as a quasi freely suspended liquid sphere and the substance in the liquid is crystallized using methods known per se. The liquid sphere is expediently held suspended within a space, which is limited from the outside by retaining elements. In a corresponding device, the retaining elements can be placed on the interior walls of a container.
