Figure 5 Phase diagram of the system K2(MoxW1-x)O4 on heating for samples synthesized at 1213  K. DSC signals (squares) for each second heating run: dotted line, melting of K2(Mo,W)2O7; solid lines, phase transformations of K2(Mo,W)O4. (Triangles indicate the hexagonal phases identified by X-ray diffraction).
