Hexagonal Ba5Ta4O15 were synthesized by a sol-gel process at temperatures of 700-900 A degrees C. The microstructure properties and morphology are studied by X-ray diffraction and scanning electron microscope. Traces of the Ba5Ta4O15 component were detected by energy dispersive X-ray analysis. A higher temperature enhanced higher atom mobility and caused the growth direction to change and created hexagonal square makes obvious good quality of samples. The visible light absorption edges of the Ba5Ta4O15 nanorods and were corresponded to band-gap energies of 4.0 eV.
