The phase diagram of a three-component system has been studied for the first time by the method of differential thermal analysis and XRF Li,Na,Pb//WO 4 . The coordinates of the invariant points are determined (42,5% Na 2 WO 4 , 47,5% Li 2 WO 4 , 10% Pb 2 WO 4 , 450°C), areas of crystallization of the initial components. The possibility of chemical synthesis of lead oxide tungsten bronzes in ionic melts of the studied system is shown.
