Multifunctional crystal growth system of modular design

Abstract

The invention discloses a multifunctional crystal growth system of modular design, relates to crystal growth and is characterized in that the system comprises a lifting and pulling mechanism, a growth mechanism, a pulling-down mechanism and a vacuum device. The lifting and pulling mechanism is arranged at the upper end of the growth mechanism, one side of the growth mechanism is communicated with the vacuum device, the bottom end of the growth mechanism is connected with the pulling-down mechanism by a lower water-cooling rod, and in the growth mechanism, crystals are produced in a lifting and pulling method, in a temperature gradient technique (TGT), in a heat exchanging method (HEM), in a molten-salt growth method, in a Kyropoulos method and in a Bridgman method by connecting with the lifting and pulling mechanism and the pulling-down mechanism, and crystals can be produced in a top-seeded temperature gradient technique (TSTGT). The multifunctional crystal growth system of modular design has the beneficial effects of regulating a temperature field by regulating the gradient and obtaining high temperature and temperature distribution required by growth of different crystals conveniently, thus increasing the research, development and production efficiency, improving the crystal sizes and quality and increasing the use ratio of devices.
