Cs在碱硬锰矿固溶体中化学固溶量的研究

Study on Chemical Solid-soluted Content of Cesium in Solid Solution of Hollandite

摘要: 以cs2CO3、BaCO3、Al2O3和TiO2为原料，通过高温固相反应，合成了单相的固溶Cs的碱硬锰矿固溶体。借助于X射线衍射(XRD)、扫描电子显微镜(SEM)和波谱分析(WDS)，研究了物相组成、Cs的化学固溶量等。结果表明：获得了单相的固溶Cs的碱硬锰矿固溶体，其Cs的最高化学固溶量约为0．26 mol，过量的Cs会生成Cs2Al2Ti2O8。

Abstract: The single phase solid solution of hollandite solid-soluted cesium was synthesized in Cs2CO3, BaCO3, Al2O3 and TiO2 as raw materials by high temperature solid phase reaction. The composition of phases and solid-soluted content of Cs were investigated by XRD, SEM and WDS. The result indicates that the largest solid-soluted content of Cs in the single phase solid solution is about 0. 26 mol, and the excessive cesium produces Cs2Al2Ti2O8.
