ABSTRACT:
Improvement in the method 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. The improved method comprises feeding the source material 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.
