Phase equilibria in the LiF-LiCl-LiVO3-Li2CrO4 quaternary system

Phase equilibria in the LiF-LiCl-LiVO 3 -Li 2 CrO 4 quaternary system have been investigated by differential thermal analysis. The eutectic composition has been determined: LiF, 7.0; LiCl, 41.5; LiVO 3 , 16.4; and Li 2 CrO 4 ,35.1 mol %. The melting point is 340°C, the enthalpy of melting is 177 kJ/kg, and the entropy of melting is 23.78 J/(mol K).
