Determination of the temperature and enthalpy of the solid-solid phase transition of caesium nitrate by differential scanning calorimetry
The equilibrium temperature of the solid-solid phase transition of high purity caesium nitrate has been measured accurately by stepwise heating and by the extrapolation to zero heating rate method. A mean value of 154.3 +/- 10.1 degrees C was obtained using two different heat flux DSC instruments. A value of 3.44 +/- 0.04 kJ mol(-1) was determined for the enthalpy of transition.
