Hydrothermal Synthesis of Na(Nb1-xTax)O3 Powder for Fabrication of Lead-Free Piezoelectric Ceramics

摘要：

　　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 ℃ for 8 hours with the addition of isopropanol.
