✦ Synopsis

The mechanism of crystal growth from the undercooled melt is studied experimentally for the naphthalene-adipic ac d system by means of a simple capillary technique. The microscopic observations for the 0.11 molefraction of naphthalene-adipic acid mixture indicated lamellar structure. The relationship between lamellar spacing, A, and crystallization velocity V was found to be PV = constant.

Mit Hilfe einer einfachen Kapillartechnik wird am System Naphthalin-Adipinsaiure der Mechanismus des Kristallwachstums aus der unterkuhlten Schmelze experimentell untersucht. Die mikroskopischen Beobachtungen zeigen fiir die 0.1 1 Molfraktion von Naphthalin-Adipinsauremischungen eine Lamellenstruktur an. Die Beziehung zwischen den Lamellenabstiinden 2 und der Kristallisationsgeschwindigkeit V wurde mit IZV = const. gefunden.
