Study on Crystallography and Electrical Property of SrV_(6-x)Al_xO_(11) Solid Solution

本文报道了ＳｒＶ－６－ｘＡｌｘＯ１１固溶体的形成条件、固溶体各组份的结晶学参数和电导性能，从结构上讨论了Ａｌ３＋部分取代对固溶体各组份晶胞参数的影响，用简单的Ａｒｒｈｅｎｉｕｓ模型拟合了ｌｎ（σＴ）与１０００／Ｔ之间的关系，并据此计算得团溶体各组份的活化能和指前因子，固溶体各组份均具有较高的室温电导率，其中ｘ＝０．６组份为最大，其值达１．０×１０－１Ｓ．ｃｍ－１．

The formation, crystallography and electrical conductivity of SrV6-xAlxO11 solid solution were described in the present paper. The effect of Al- doping on cell parameters of each composition in this series was discussed with respect to their structure. The relationship between In(σT) and 1/T can be fit depending on a simple Arrhenius model, from which the activation energy and pre-exponential factor for each composition were calculated. All these samples exhibited higher electronic conductivity at roon temperature. The maximal one had the conductivity of 1.0×10-1S.cm-1 for the composition with x=0.6.
