Description
Diese Aufgabe wird gelöst durch das Verfahren gemäß Anspruch 1 und die Vorrichtung gemäß Anspruch 4.
ρ das spezifische Gewicht der Schmelze bei der
g die Erdbeschleunigung,
R der innere Radius des Kapillarrohres,
Kr eine von der Art der Schmelze und der Form des Kapillarendes abhängige Konstante bedeuten.
Ke eine von der Art der Schmelze und der Form des Kapillarendes abhängige Konstante bedeuten.
entsprechend
P= 9,7 g/h.
Falls man einen einzelnen Zylinder, einen einzelnen Faden oder eine Platte herstellen will, verwendet man eine Düse mit nur einer einzigen öffnung.
Man erhält Einkristalle einer gewünschten Form ohne oder mit nur sehr einfacher Bearbeitung,
das Verfahren ist kontinuierlich,
mit geeignet orientierten Keimen kann man Einkristalle in jeder Kristallrichtung des betreffenden Einkristalls ziehen,
Herstellung eines NaCI-Einkristalls
Herstellung eines Si-Einkristalls
Züchtung eines Einkristallfadens aus NaCl
Herstellung eines Rohres aus Saphir
