ABSTRACT:
The invention relates to a stabilization device for stabilizing dendritic web seed buttons during initiation of crystal growth from a float zone melt. The invention includes angular maintenance means for maintaining a constant angular orientation between the axis of a growth initiation seed and the upper surface of a web button during withdrawal of the web button from the melt. In the preferred embodiment, the angular maintenance means includes an adjustable elevation tube which surrounds the seed, the weight of which may be selectively supported by the seed button during web button withdrawal.
