Singularities of the p-T curve universal equation for phase transitions of the first kind

Realization of the sublimation temperature point of carbon dioxide

“…Therefore, the third constant allows better approximation but constant B in this case does not correspond to the latent heat of sublimation. An alternative way to describe T(p) is the Zhokhovskii equation [9], which describes T(p) along the coexistence curve between two points -initial and final -with T and p known. The Zhokhovskii equation does not need the assumption that L is constant over the range, but it requires to determine some empirical constants.…”
