Evolution of the light scattering and electrical properties of the tungstic acid during the gelation process has been investigated. The scattered light becomes anisotropic and the depolarized scattering grows strong around 2 hours after the beginning of gelation. On the other hand, the resistance shows a steady increase. With the results obtained from the present study, we concluded that the light scattering mechanism changes from the Rayleigh scattering to the Mie scattering with the progress of gelation.
