Structural and microstructural characterization of Co-hydrotalcite-like compounds by X-ray diffraction

Nanosized spinel oxide catalysts for CO-oxidation prepared via CoMnMgAl quaternary hydrotalcite route

“…A homogeneous mixture of oxides with very small crystal size, stable against thermal treatments, and deactivation could be obtained easily by thermal treatment of hydrotalcite-type precursors [14,15]. Hydrotalcite-like compounds (HTlcs) have received considerable attention in the recent decades due to their applications related to heterogeneous catalysis, due to their high surface area and reactivity [14][15][16][17][18]. Addition of cobalt to the hydrotalcite cationic sheet increases the crystal perfection due to increasing crystallite size and decreasing microstrain [16].…”

The study of Co-Mn-Mg-Al hydrotalcite system and their metal oxides as catalysts was investigated only as ternary systems.…”

Ferroelectric properties of mixed bismuth layer-structured Na0.5Bi8.5Ti7O27 ceramic and SrxNa0.5−x/2Bi8.5−x/2Ti7O27 solid solutions

“…The crystalline phase of the crushed sample was identified by the X-ray powder diffraction (XRPD) with Cu K␣ radiation. Also, the lattice parameters of the samples were calculated by using the least squares method [9]. The microstructure of the samples was examined using a field emission scanning microscopy (FE-SEM).…”

Effects of V Substitution on Dielectric and Polarization Properties for Sr0.5Bi2.25Na1.25(Nb3−xVx)O12 Ceramics

“…Subsequently, these pellets were sintered in the temperature range of 900°–1100°C for 2 h in air. The crystalline phases of the crushed samples were identified using the X‐ray powder diffraction (XRPD) method to ensure the formation of a single phase, and the lattice parameters of the sample were calculated by the least squares method 8 . The bulk densities of the samples were determined by the Archimedes method.…”
