Figure 6 Phase diagram of the system K2(MoxW1-x)O4 on cooling samples synthesized at 1213  K. DSC signals (squares) for each second cooling run: dotted curve, crystallization of K2(Mo,W)2O7; solid curves, phase transitions of K2(Mo,W)O4. (Triangles indicate hexagonal, circles indicate orthorhombic and diamonds indicate monoclinic phases identified by X-ray diffraction).
