VERFAHREN UND VORRICHTUNG ZUR AUSKRISTALLISATION EINER IN EINER FLUESSIGKEIT GELOESTEN SUBSTANZ IM ZUSTAND DER SCHWERELOSIGKEIT

摘要

To reduce, as far as possible, the extent of the structural defects arising in the single crystals which have crystallised out, it is intended that the liquid is held during the crystallisation as a quasi-freely suspended sphere 6 of liquid and the substance in the liquid is crystallised out by means of methods known per se. Advantageously, the sphere 6 of liquid is held in suspension within a space region which is bounded from the outside by retaining elements 3. With an appropriate device, the retaining elements 3 can be fitted to the inner walls of a container 1. ……
