Phase diagrams of systems containing molybdates of iron, cobalt and nickel

Making use of the methods of X-ray phase, including high-temperature, differential thermal, thermogravimetric and thermo-optical analyses, the phase diagrams of the Fe2(MoO4)3-CoMoO4, Fe2(MoO4)3-CoMoO4 and Fe2(MoO4)3-NiMoO4 systems are constructed. They are eutectic with narrow zones of compound homogeneity. In the CoMoO4-NiMoO4 system, two series of continuous solid solutions are formed
