DISPOSITIF DE CRISTALLOGENESE A PISTON

摘要

In a piston-type crystal growth unit, having a piston (16) which can move in the crystal growth direction within a crucible (10) containing a liquid-covered seed (12), piston displacement is effected by the liquid (14) to be solidified. Preferably, the piston displacement system consists of a float (18) connected to the piston (16) by a piston rod (17) or by a rack and pinion mechanism.
