The equilibrium solubilities of CsNO₃ in CsNO₃-C₂H₅OH-H₂O ternary system at -10℃, 10℃, 30℃ and 50℃ have been studied using a self-made microdevice for solubility determination. The density and refractive index of the solutions were also determined. The equilibrium phase diagram is given and indicates that the equilibrium solid phase is CsNO₃. The solubility, density and refractive index of the solution were correlated to the alcohol content according to the experimental equation ln Y=A₀+A₁x+A₂x²+A₃x³.
