Article Preview

Hydrothermal method was used to synthesize the Na(TaxNb1-x)O3 (x = 0.1-0.5) powders with the addition of isopropanol. The phases of the obtained powders were confirmed by XRD. The morphology and particle size were observed by FE-SEM. The specific surface areas were measured by multipoint BET technique. The presence of water and organic group were determined by (FT-IR) spectroscopy. The results indicate that the pure Na(TaxNb1-x)O3 (x = 0.1-0.5) powders with perovskite structure and fine particles were successfully synthesized by hydrothermal method at 240 °C for 8 hours with the addition of isopropanol.
