Abstract
The present disclosure provides a method for growing scintillation crystals with multi-component garnet structure. According to the method, through weight compensating for reactants, introducing a flowing gas, adopting a new temperature field device, and optimizing process parameters, problems such as component deviation and crystal cracking during the crystal growth can be solved to a certain extent, and grown crystals have consistent performance and good repeatability.
Claims20
A method for growing a crystal, comprising:
- placing reactants into a temperature field device of a crystal growth device, wherein
- the crystal growth device includes an open hearth and the hearth has gas exchange with atmospheric environment;
- the temperature field device is positioned in the hearth;
- the temperature field device is sealed and has no gas exchange with the atmospheric environment;
- an observation unit is mounted on the temperature field device;
- the observation unit includes a through hole which is communicated with an internal chamber of the observation unit and the temperature field device;
- and
- the through hole is configured for gas passing;
- introducing a flowing gas into the temperature field device through the through hole after sealing the temperature field device;
- and
- activating the crystal growth device to grow the crystal.
