原始语种摘要: Abstract(#br)Ruby single crystals were synthesized from MoO 3 , PbF 2 , and PbF 2 –B 2 O 3 fluxes. Mo-based flux gave hexagonal bipyramidal crystals. On the other hand, plate-like crystals were given from Pb-based fluxes. The specific surface free energy of the ruby single crystal was experimentally obtained using contact angle of liquid droplets on the crystal surfaces, and compared with the length of normal line to the face from the center of the crystal, h i . The proportions of the specific surface free energies to h i ’s were constant for different faces of each individual ruby crystal synthesized from Mo-based flux. This result looks to satisfy the Wulff's relationship. However, the proportions were not equal for respective crystals from Mo-based flux, which is considered to result...
