Abstract

A new niobate crystal Ba4Na2VNb9O30 was synthesized in BaO−Na2O−V2O5−Nb2O5 system for the first time. Its shape, optical properties, melting point and chemical stability wer estudied. X-ray powder diffraction study determined that this compound assumes a tetragonal tungsten bronze structure with space group P4 bm (100) and lattice parameters a=b=12.4275(2), c=3.970(3). The new compound may be one kinds of photorefractive crystals.
