Commercial-purity dichlorobenzene was purified using a columnar distillation system. The equilibrated grain boundary groove shapes for purified dichlorobenzene (DCB) were directly observed by using a temperature gradient stage. From the observed grain boundary groove shapes, the Gibbs-Thomson coefficient and solid-liquid interfacial energy of purified DCB were determined to be (6.2 0.6) × 10-8Km and (29.3 4.4) × 10 -3Jm-2 with the present numerical model and the Gibbs-Thomson equation, respectively. The grain boundary energy of the DCB phase was determined to be (54.1 9.2) × 10-3Jm-2 from the observed grain boundary grooves. The thermal conductivity ratio of the liquid phase to the solid phase was measured to be 0.94. © 2007 IOP Publishing Ltd.
