ABSTRACT:
A method for growing large, shaped, oriented crystals and an apparatus for cooling the seed crystal so that a portion thereof remains solid throughout the crystal growth process. The critical and time consuming process of seeding crystals under continuous supervision is eliminated. The unmelted portion of the seed crystal is maintained at a temperature below its melting point through a seed temperature control apparatus which utilizes a pool of a substantially liquid metallic material as a heat transfer medium. The pool is contained in a reservoir formed in a thermal energy conductive base member in which the growth vessel is disposed.
