ResumoCrack-free, transparent and colorless fiber single crystals with the size of 0.8–1.2 mm in diameter and 20–80 mm in length were grown from the melts of NaxCa2.5 − x2Mg2V3O12 where x = 0.0–1.0 by the micro-pulling-down method. The crystals grown from stoichiometric, NaCa2Mg2V3O12, and Na+-rich (x < 1.0) melt in air were transparent and gray colored. It was found that lower the x value, higher is the uniformity of lattice parameters of the solidified fraction. Maximal uniformity was achieved for the Ca2.5Mg2V3O12 crystals of less than ±0.001 Å.
