Abstract

The invention belongs to the technical field of crystal growth, and relates to a falling temperature method crystal growth system capable of maintaining constant supersaturation. The system comprises a detection unit composed of a tension sensor and a thermoelectric couple, a control unit composed of a signal processor and a microcomputer, and an execution unit composed of a temperature controller; the system can realize real-time measurement of mass variation of the growing crystal, and can regulate the water bath to cool according to the variation, so as to make the increment of supersaturation caused by temperature falling of solution equal to the decrement of supersaturation caused by crystal growth, thus, steady and rapid growth of crystal under constant supersaturation is realized, generation of a growth layer and an inclusion is inhibited, and quality of the grown crystal is improved.

Description

technical field

[0001] The invention belongs to the technical field of crystal growth, and relates to a cooling method crystal growth system for maintaining constant supersaturation, which is suitable for stable, fast and high-quality growth of crystals. Background technique

[0002] The cooling method is a commonly used method for growing crystals in solution. During the crystal growth process by the cooling method, it is crucial to keep the supersaturation of the solution constant, because the fluctuation of the supersaturation of the solution may lead to the generation of growth layers and even the formation of inclusions. Therefore, maintaining a constant supersaturation of the growth solution is a prerequisite for growing high-quality crystals.

[0003] In order to ensure the stable and rapid growth of crystals at a constant supersaturation, real-time measurement and control of the supersaturation of the solution is required. At present, the methods for real-time meas...
