摘要
采用1600℃固相反应法制备了Ba0.8Sr0.2Ti0.6Zr0.3Mn0.1O3多晶。通过x射线衍射技术证实了该化合物为无杂质的单相结构。制备的化合物结晶为Pm-3m空间群的立方结构,细化晶格参数为a = b = c = 4.0253 Ǻ, α = β = γ = 90°。用GSAS软件对粉末XRD数据进行Rietveld细化,用powder X软件对实验数据峰进行索引。
Structural analysis of Ba0.8Sr0.2Ti0.6Zr0.3Mn0.1O3 ceramics
Polycrystalline Ba0.8Sr0.2Ti0.6Zr0.3Mn0.1O3 was synthesized by solid-state reaction at 1600°C. The single phase formation of the compound without any impurities was confirmed by the X-ray diffraction technique. The prepared compound crystallized to a cubic structure with a space group of Pm-3m and the refined lattice parameters were a = b = c = 4.0253 Ǻ, α = β = γ = 90°. Rietveld refinement was carried for the powder XRD data using GSAS software and the experimental data peaks were indexed by Powder X software.
