Crystal pulling method—synthesis principle
The seed crystal is in contact with the molten liquid surface of
the raw material, so that the top of the melt is crystallized on
the seed crystal in a supercooled state, and the seed crystal rod
is pulled up and rotated to grow a cylindrical gem crystal. The
pulling speed of corundum is 6-25mm per hour.
Feature:Elongated bubbles or curved ribbons may be seen in the
crystals produced by the crystal pulling method.
