Rietveld refinement of the BaTiO3 from X-ray powder diffraction
The ferroelectric ceramic BaTiO3 was synthesized at 1000 ℃ for 5 h. The structure of the system under study was refined on the basis of X-ray powder diffraction data using the Rietveld method. The system crystallizes in the space group P4mm (99). The refinement of instrumental and structural parameters led to reliable values for the Rp, Rwp and Rexp. We use the TOPAS software of Bruker AXS to refine this ceramic powders and show its conformation.
