Iron(II) chloride (melting point 677°C) and potassium chloride (melting point 776°C) form the compounds KFeCl3 and K2FeCl4 at elevated temperatures. KFeCl3 melts congruently at 380°C and K2FeCl4 melts incongruently at 399°C. Eutectics are formed with compositions x = 0.38 (melting point 351°C) and x = 0.54 (melting point 393°C), where x is the mole fraction of FeCl2. The KCl solubility curve intersects the K2FeCl4 curve at x = 0.34. Sketch the phase diagram. State the phases that are in equilibrium when a mixture of composition x = 0.36 is cooled from 400°Cto 300°C.
