摘要

Seedless crystallization of molten Ge and GaSb droplets was achieved under micro- gravity occurrig in a drop-shaft capsule. It was observed that the spherical droplets of Ge or GaSb moving with inertia in Ar atmosphere, were solidified instantaneously when They collided with the container quartz wall under supercooling conditions. X-ray dif- Fraction pattern of these solidified samples showed clear Laue spots signifying a single- Crystal structure, while Ge or GaSb solidified in crucibles under normal gravity did not Show Laue spots.
