Structural and optical study of perovskite nanoparticles MSnO3 (M = Ba, Zn, Ca) obtained by a wet chemical route

Strontium-Containing Barium Titanate-Modified Titanium for Enhancement of Osteointegration

“…The high-resolution spectra analysis of Ba and Sr is presented in Figure d,e, respectively. The peaks at 778.68 and 793.95 eV corresponded to Ba atoms in the perovskite structure of the films, whereas the divided peaks centered at 794.88 and 779.55 eV corresponded to the Ba atoms in the nonperovskite structure of the coatings. , The ratios of the perovskite structure versus nonperovskite structure for each peak are shown in Table . Similarly with Ba, the 3d 5/2 and 3d 3/2 peaks of Sr can be divided into peaks (132.32 and 134.20 eV) and (132.87 and 134.70 eV) attributed to perovskite and nonperovskite structure, respectively. , Furthermore, the contents of the perovskite structure in the coatings showed the following trend: BST-3 > BST-2 > BST > BTO (Table ), which is in agreement with the XRD result.…”

Formation of ceramic bodies using submicron msno3 (m = ba, zn, ca) particles and evaluation of their electric behaviour in different atmospheres

“…MSnO 3 (M = Ba, Zn, Ca) powders were obtained by the polymer complex method described in previous work [18,54]. The crystalline structures of the synthesized particles were determined with X-ray diffraction (XRD) using the PANalytical X'Pert PRO diffractometer with a Cu source having Kα 1 = 1.540598 Å and Kα 2 = 1.544426 Å and working voltage and current of 45 kV and 40 mA, respectively.…”

The crucial role of defect structure in understanding the electrical properties of spark plasma sintered antimony doped barium stannate

“…Barium stannate (BaSnO 3 , BSO), a perovskite-type alkaline Earth stannate, is distinguished among other perovskite oxides by its ideal cubic crystal structure (space group: Pm m 3 ¯), Goldschmidt factor close to 1 [11], thermal stability up to 1000 °C, non-toxicity and easy methods of preparation [4,5,12,13]. Its crystal structure consists of Ba 2+ ions on the corners of the cube, with each Ba 2+ ion coordinated by twelve O 2− ions forming cubic close-packed lattice, while Sn 4+ ions are occupying octahedral holes created by O 2− ions [13,14]. Undoped BSO exhibits semiconductor-like behavior with wide band gap in the range of 3.1-3.4 eV [3,4,12,13,[15][16][17][18][19], which can be modified by careful replacement of Ba 2+ or/and Sn 4+ with aliovalent cations [3-6, 13, 15].…”
