摘要
Crack-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-x/2Mg2V3O12 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 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 Angstrom.
