Compared with Czochralski method SGG single crystal growth with crucible capsuled vertical Bridgman method can improve crystal production and lower the cost efficiently.

This paper reported a new procedure for growth of 5 inch diameter LT crystal in Ir-crucible by using Czochralski method.

In the Czochralski crystal growth process, the main method is regulating the pulling speed and heater temperature to track the target curves, in order to achieve the diameter growth of crystal.
