The vibrational properties of WO3 ceramics in the 30–300 K temperature range were probed by Raman spectroscopy. Starting with WO3 ceramics at room temperature presenting monoclinic (V) and triclinic (VI) mixed phases, structural transitions related

The coexistence of phases in WO3 ceramics sintered within the 600–1000 °C temperature range is investigated using Raman microprobe spectroscopy. The analysis of vibrational modes indicates the existence of triclinic (VI) P1 and monoclinic (V) P21/

Tungsten trioxide sintered wafers were prepared from WO3 powder obtained when ammonium paratungstate is decomposed in air at moderate temperature. Two wafer series of five samples were sintered under the same conditions in the temperature range 600
