The phase diagram of the Bi2WO6-TeO2 pseudo-binary system has been est
ablished from 60 to 100 TeO2 mol %, using DSC and XRD experiments. Thr
ee fixed temperature events were found : one eutectic and two peritect
ics. The new compounds Bi2Te2WO10 and Bi2Te5WO16 were identified and c
haracterized by X-ray diffraction.
