Synthesis of Single-Phased BaTi2O5 Powders by Arc-Melting

Abstract:

Article Preview

Arc-melting was employed to synthesize BaTi2O5 powders by fast melting the reagent mixture of BaCO3 and TiO2 with different molar ratios (0.90~1.05:2). The influence of molar ratios of BaCO3 to TiO2 on the phase of the powders derived from arc-melting was investigated by X-ray diffraction and Raman spectra. When the molar ratio was larger than 0.95:2, a little amount of Ba-rich compound Ba2TiO4 was produced besides the main phase of BaTi2O5. Ti-rich compound Ba6Ti17O40, BaTi2O9 and TiO2 began to appear at the ratios ranging from 0.90:2 to 0.95:2. Single-phased BaTi2O5 powders were obtained by arc-melting the reagent mixture with the molar ratio of 0.95:2.
