Micro-pulling and shoulder expanding at cooled center is a sapphire
growth method, which is also called micro-pulling rotation Kyropoulos.
The is an improved method based on Kyropoulos Method and Pulling Method
by Institute of Composite Structures from the Harbin Institute of
Technology. It is used to grow large size crystal. Crystal growing
system includes control system, vacuum system, heating body, cooling
system and thermal protection systems. The following a picture, which is
a schematic shoulder cold heart to put the system trace Czochralski
method,
SAPMAC grown single crystal, the outlook is usually pear-shaped,
crystal diameter crucible can grow to more than the inner diameter of
the small size of 10 ~ 30mm. The seed is processed into split shape, use
seed clips at the bottom of the heat exchanger. Rotating and pulling
the heat exchanger can be accomplished seed fixed, crystals, and the
exchange interaction between the heat exchanger, crystal and melt.
Tungsten crucible is widely used in sapphire growth furnace, including SAPMAC method.
