摘要: 采用水热晶化法合成出SrTi1-xSnxO3系列化合物,并对其结构进行了表征。结果表明,随着Sn含量的增加,产物的晶胞体积增大,红外吸收谱带发生劈裂,并向高波数方向移动;SrTi1-xSnxO3化合物粒度较小,其中常含有少量有机物和吸附水,可以Ti(OC4H9)4为Ti源直接合成。

Abstract: Sn-containing complex oxides,SrTi1-xSnxO3(O≤x<0.8)were synthesized under hydrothermal conditions. The products were identified by XRD, TGand IRtechniques. The results showed that the products could be synthesized at higher pH, and the compositions of the products were not the same of the mixture while there were some Sr and Sn left in the solution.The lattice volume increased with the increasing of the amount of Sn incorporated in the lattice of SrTiO3. The IRabsorption bands of the SrTi1-xSnxO3 were split,and moved towards blue with the increasing of the amount of Sn in SrTi1-xSnxO3 compounds.The products synthesized with Ti (OC4H9)4 contained little absorbed water and organic substance,which was lost at 350℃. The crystal sizes were small and even.
