Özet
The grain boundary groove shapes for solid aminomethylpropanediol in equilibrium with eutectic aminomethylpropanediol-neopentylglycol liquid were directly observed by using a horizontal temperature gradient stage. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of solid aminomethylpropanediol in equilibrium with eutectic aminomethylpropanediol-neopentylglycol liquid have been determined to be (5.3 ± 0.5) × 10 -8 K m, (8.5 ± 1.3) × 10 -3 J m -2 and (16.8 ± 2.9) × 10 -3 J m -2 , respectively. © 2008 Elsevier B.V.
