Resumen:
Ice grain boundary energies γgb relative to the free surface energy γs were determined by studying the topographic details revealed by plastic replicas of the ice grain boundary groove-free surface with a Laser Confocal 3D Microscope. The samples analyzed were high purity ice bicrystals, with /Ψ tilt grain boundaries, annealed at -18°C. Values obtained of γgb/γs were analyzed using coincidence site lattice (CSL) theory. Significant correspondence was found between the γgb/γs values and the planar density (Gamma) of coincident sites on the interface plane. The results show that γgb/γs depends on the GB inclination and may be up to one order of magnitude different
