Crucible-die assemblies for growing crystalline bodies of selected shapes

Apparatus for use in a system for growing crystalline bodies of selected shape from a melt which is delivered from a crucible to a liquid/solid growth interface by a capillary die, said apparatus comprising a crucible and capillary die combination in which (1) at least a part of the die is an integral portion of the crucible and (2) the crucible is an essential portion of the die, said crucible being (a) open at its top end, (b) closed at its bottom end and (c) having a side wall defining an interior space for containing a melt, said crucible side wall (i) having an upper end defining at least one edge surface of the die, said side wall (ii) also forming one boundary surface of at least one capillary space which has one end communicating with said interior space and the other end terminating at said upper end.
