Abstract: Nanocrystalline Ba2NdSbO6, a complex cubic perovskite metal oxide, powders were synthesized by a self-sustained combustion method employing citric acid. The product was characterized by X-ray diffraction, differential thermal analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy, transmission electron microscopy and scanning electron microscopy. The as-prepared powders were single phase Ba2NdSbO 6 and a mixture of polycrystalline spheroidal particles and single crystalline nanorods. The Ba2NdSbO6 sample sintered at 1500°C for 4 h has high density (̃ 95% of theoretical density). Sintered nanocrystalline Ba2NdSbO6 had a dielectric constant of ̃ 21; and dielectric loss = 8 × 10-3 at 5 MHz. © Indian Academy of Sciences.
