FIELD: crystal growth.
SUBSTANCE: diaphragm is made of two interconnected metallic disks arranged one above the other. The bottom disk is mounted at the top boundary of the solution zone of charge and provided with an opening at the center. The top disk is mounted at the bottom boundary of the zone of crystal growth and provided with openings distributed throughout the surface of the disk. The diameters of the openings in the bottom disk are 1-75% of the diameter of the disk.
EFFECT: enhanced quality of crystals.
