DEVICE FOR GROWING PROFILED CRYSTALS FROM SOLUTION Russian patent published in 2017 - IPC C30B7/00 C30B29/60 

Abstract RU 2637018 C1

FIELD: chemistry.

SUBSTANCE: device comprises a hermetic crystalliser 3, a growth chamber 1 of rectangular cross-section with a seed crystal 2 and a solution supply system to the crystal 2 including a non-moving pump 5 for supplying a saturated solution to the growth zone of the crystal 2 and a plate 6 arranged above the growing surface of the crystal 2, which is reciprocable in the vertical direction and the progressivey upward direction as the crystal grows, having a width and a length less than the width and the length of the growth chamber 1 so that between the plate 6 and the walls of the chamber 1 there are slots connected to the actuator 7 by, at least, one variable length rod 8 with a fastening unit 9 to the plate 6 allowing the angle between the plate 6 and the rod 8 to be varied. It is also possible to make the plate 6 with holes for additional passage of the solution.

EFFECT: simplification of construction, improvement of conditions for growing.
