Abstract

In this study we sintered NaSbO₃ compound at 860 °C from Na₂CO₃ and Sb₂O₃, detailed structural and microstructural of the compound were studied. Refinement of the X-ray diffraction (XRD) patterns by method of Rietveld indicate that the crystal structure of NaSbO₃ belongs to the trigonal system with hexagonal symmetry, space group R3‾(No.148), lattice parameters a = 5.2944(4) Å, c = 15.9469(8) Å and volume V = 387.124(0) ų with Z = 6. Scanning electron microscopy (SEM) analysis displayed that sintered samples at temperatures lower than 750 °C have a favorable effect on the homogeneity of the samples.

Keywords: Perovskites, alkaline metal antimonates, Chemical synthesis, X-ray diffraction.
