Abstract
A new niobate crystal was synthesized for the first time in BaO−NaO−Cr2O3−Nb2O3, ystem by the solid state reaction and the flux method. The new compound was studied by X-ray diffraction, electron probe, X-ray microanalysis, chemical analysis and SEM. The result of X-ray powder diffraction show that Ba5NaCr0.5 Nb9.5O30 belongs to the tetragonal tungsten bronze structure, with space group P4 bm(100) and lattice parameters a=b=12.4450(2)A, c=3.9931(2)A and Z=1. The X-ray powder diffraction lines of the compound were well indexed.
