Study on the NaCl-CaCl2 Binary System

By use of micro-DTA technique as well as ambient and high temperature X-ray analysis the phase diagram ofNaCl-CaClhas been checked.It is.a simple eutectic system with a solid solubility in the sodium chloride side.Theeutectic point is at 773K,49 mol% NaCl.The experimental results,especially those of the X-ray diffraction studies haveshowed that the incongruent compound 4NaCl-CaCldoes not exist in the NaCl-CaClsystem.
