Abstract
There are two known tungstates – In6WO12 and In2(WO4)3 – in the In2O3–WO3 system. Transport properties of ceramics samples of both tungstates were investigated using impedance spectroscopy as a function of temperature and oxygen activity, the EMF-technique, and Tubandt-type experiments in cells with Pt and WO3-electrodes. Conduction in In2(WO4)3 was shown to be primarily ionic, but no evidence of In3+ conduction was observed. In6WO12 is n-type semiconductor with relatively low conductivity.
