Structural Investigations of Low Thermal Conductivity Materials

We wish to exploit the ability of neutrons to locate light atoms in the presence of heavy atoms to investigate the structural properties of new defect pyrochlores with low thermal conductivity that are designed to act as thermal insulation in thermal batteries. Using ion exchange techniques, we have produced mixed ammonium-caesium materials [(NH4)1-xCsxTa1-yNbyWO6 0

我们希望利用中子在重原子存在下定位轻原子的能力，研究新型低导热缺陷烧绿石的结构特性——这类材料被设计用作热电池中的隔热材料。通过离子交换技术，我们制备了混合铵-铯材料[(NH4)1-xCsxTa1-yNbyWO6 0
