Abstract

Dielectric relaxation measurements of tungsten hydrates WO₃·H₂O and WO₃·2H₂O were performed in a broad frequency range 1 MHz-10 GHz. The dielectric spectra exhibit two dielectric relaxations due to the reorientation of interlayer and coordinated water. One explanation of these mechanisms with respect to the experimental results is proposed. The influence of WO₃ solid network on water mobility has been considered.
