摘要
We have observed the growth morphology of NdAl3(BO3)4 (abbreviation: NAB) grown from BaO-B2O3 solvent. The relationship between the growth morphology and the structure of the crystal was first analyzed by the Donnay-Harker theory and the Periodic Bond Chain (PBC) theory. The cause of the inherent tendency for the easy appearance of the habit faces was explained.
