Analysis ofCrystal Structure the BaTiO3 and ZrO2-doped (Bi0.5Na0.5)TiO3 with X-ray Diffraction Techniques Using the Rietveld Method | Chapter 7 | New Visions in Science and Technology Vol. 3

The crystal structures of a (Bi0.5Na0.5)TiO3 (BNT) compound doped with BaTiO3 (BT) and ZrO2 were investigated. (Bi0.5Na0.5)0.93Ba0.05Zr0.02TiO3 (BNBZT1), (Bi0.5Na0.5)0.90Ba0.05Zr0.05 (BNBZT2), and (Bi0.5Na0.5)0.85Ba0.05Zr0.10TiO3 (BNBZT3) were the three types of samples prepared (BNBZT3). In a solid-state reaction approach, the samples were generated using Bi2O3, Na2CO3, BaCO3, TiO2, and ZrO2 powders as basic ingredients. In an agate mortar, the fundamental ingredients were mixed for 3 hours. A 3,000 psi hydraulic press was utilised to make pellets from a precursor. Pellets were sintered for 5 hours at 1000°C after being calcined for an hour at 300°C. The materials were characterised using X-ray diffraction techniques based on the Rietveld method and Raman spectroscopy. BNT doped BT and ZrO2 had a tetragonal structure, space group I4/mcm, Volume I, No.140, with lattice parameters a = b = 5.519 (2), c = 7.808 (4) (BNBZT1), a = b = 5.512 (1), c = 7.798 (5) (BNBZT2), and a = b = 5.513 (1), c = 7.800 (2) ( (BNBZT3). By partial substitution of cations (Bi, Na)2+, Ba2+ and Zr4+ cations entered the BNT crystal structure in these three samples. However, some Ti3+ cations in BNBZT3 were replaced by Zr4+. BNBZT1, BNBZT2, and BNBZT3 have the ionic configuration (compound) (Bi0,45Na0,48)0,93Ba0,05Zr0,01TiO3, (Bi0,41Na0,49)0,90Ba0,05Zr0,03TiO3 and (Bi0,42Na0,43)0,85Ba0,05Zr0,01(Ti
