摘要

用热重法研究了仲钨酸铵5(NH4)2O.12WO3.5H2O在氢中的分解，并建立了六方钨铜铵相(NH4)xWO3(x ~ 0.25)的形成。粉末x射线衍射仪研究、电导率、磁化率和反射光谱测量表明，该相与相应的由钾和铷形成的钨青铜具有等结构和等电子特征。

Preparation and characterization of a hexagonal ammonium tungsten bronze phase (NH4)xWO3

The decomposition of ammonium paratungstate 5(NH4)2O.12WO3.5H2O in hydrogen has been studied thermogravimetrically and the formation of a hexagonal ammonium tungsten bronze phase, (NH4)xWO3(x∼0.25) established. Powder X-ray diffractometer studies, and measurements of electrical conductivity, magnetic susceptibility and reflectance spectra show that this phase is both iso-structural and iso-electronic with corresponding tungsten bronzes formed by potassium and rubidium.
