摘要

本文介绍了在cs20 - al2o3 - tio2体系中存在荷兰石相的浓度极限的研究结果。通过燃烧柠檬酸盐-硝酸盐组合物，得到了许多不同比例的铯、铝和钛样品。利用x射线相分析和扫描电镜研究了所得材料的相组成和微观结构。电学性能研究发现，Cs1.16Al1.84Ti6.33O16 （T = 750℃时σ = 5.45 × 10-5 S/cm）具有最高的比电导率。

Electrical Conductivity of Solid Solutions Based on Hollandite Obtained in the Cs2O–Al2O3–TiO2 System by the Combustion Method

This article presents the results of a study of the concentration limits of the existence of the hollandite phase in the Cs₂O–Al₂O₃–TiO₂ system. A number of samples with different ratios of cesium, aluminum, and titanium are obtained by combustion of citrate–nitrate compositions. The phase composition and microstructure of the obtained materials are studied using X-ray phase analysis and scanning electron microscopy. When studying the electrical properties, it is found that the Cs_1.16Al_1.84Ti_6.33O₁₆ (σ = 5.45 × 10^–5 S/cm at T = 750°C) has the highest specific electrical conductivity.
