稀土双(11-钨硅酸)钾的质子导电性研究(英)

Investigation on the Proton Conductivity of Bis(11-tungstosilicate) Lanthanates of Potassium

研究了K13［Ln（SiW11O39）2］nH2O（Ln=La，Ce，Pr，Nd，Sm，Gd）的质子导电性研究表明其导电性不仅与物质本性有关，也与外界条件如温度、频率等有关，不同结构的杂多化合物给出不同结构的质子导电性．总结了质子导电性随温度、结晶水数目、频率的变化总趋势．基于实验数据得出一些重要结论，所得数据未见文献报道．

Proton conductivity of K13 [ Ln(SiW11O39)2 ] )nH2O(Ln = La, Ce, Pr, Nd, Sm, Gd) have been measured. It is dependent not only on the nature of compounds itself, but also on main external factors such as temperature and frequency. Heteropoly compounds with differ ent structures give different conductivity. The general trend of proton conductivity changing with the hydration numbers, frequency and temperature is summarized. Some important conclusions have been drawn based on experimental measurements. The resulting data have not been found in the reported literature.
