The method of the invention for the crystallization of one or more compounds from a solution or melt containing the same is carried out by exposing said solution or melt for the effect of an electric field. The method is mainly characterized by the steps of using a metal electrode as one electrode and said solution or melt to be crystallized as the other electrode. An insulation layer is used between the electrodes, the solution is connected to a conductor, and the electrodes are connected to a power source as a result of which the solution or melt to be crystallized is polarized and crystallized in controlled conditions. The invention is also concerned with an apparatus, which is characterized by a vessel containing a solution or melt to be crystallized, a metal electrode, another electrode consisting of said solution or melt to be crystallized, and an insulation layer between the electrodes. The solution is connected to a condutor and the electrodes are connected to a power source. |
