ABSTRACT:
Improvement in apparatus for growing crystalline materials by seed pulling from a melt whereby crystalline product produced is substantially free of voids and/or inclusions which were previously caused by the continuous feeding operation. Source material is fed through a bed of particulate refractory material whereby entrained gases in the melting feed material are eliminated thereby resulting in a crystalline product which is substantially free of voids and inclusions. The apparatus improvement comprises providing an inner container for solid particulate material within a crucible and spaced therefrom which container has one or more openings at the bottom thereof to permit exiting of liquid therethrough to the crucible. Such apparatus is particularly adapted to effectuate the process improvement of the invention.
