Abstract The phase diagram of the system NiO-WO3 was established by means of differential thermal analysis (DTA) supported by photoemission electron microscopy (PhEEM) and X-ray diffraction (XRD). The only compound, NiWO4, melts incongruently (peritectic decomposition) at 1420° C and forms a eutectic with WO3 at 73 mol % WO3 and 1245° C. Primary phase crystallization as well as eutectic and peritectic solidification were studied by the comparison of the DTA measurements and the phase intergrowth morphologies as observed by PhEEM. The experimental liquidus lines are briefly discussed with reference to the calculated values.
