METHOD OF CRYSTAL GROWING FROM SOLUTION AT CONSTANT TEMPERATURE Russian patent published in 2020 - IPC C30B7/02 C30B35/00 B01D9/02 

FIELD: growing of artificial crystals.

SUBSTANCE: invention relates to cultivation of artificial crystals from solutions. In a method of growing a crystal from a solution at a constant temperature, including withdrawal and subsequent return of solution to the crystallizer, total volume of solution in crystallizer is divided into two interconnected parts, in the first of which there maintained is constant level and concentration of solution, and in the second one, level of solution is changed by supply of gas under pressure, displacing solution volume from the second part to the first one. To maintain a constant level in the first part, a volume of the solution, which is equal to the volume of the solution displaced from the second part, is discharged from it into a condensate collector placed outside the crystallizer. Gas is supplied into the second part manually or automatically. Air can be used as gas.

EFFECT: high quality of the crystal while simplifying the process.
