Özet
The grain boundary groove shapes for equilibrated solid aminomethylpropanediol, 2-amino-2 methyl-1.3 propanediol (AMPD) with its melt were directly observed by using a horizontal temperature gradient stage. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient (Gamma), solid - liquid interfacial energy (sigma(SL)) and grain boundary energy (sigma(gb)) of AMPD have been determined to be (5.4 +/- 0.5) x 10(-8) Km, (8.5 +/- 1.3) x 10(-3) J m(-2) and (16.5 +/- 2.8) x 10(-3) Jm(-2), respectively. The ratio of thermal conductivity of equilibrated liquid phase to solid phase for the AMPD has also been measured to be 1.12 at the melting temperature.
