Equilibrium background of processes iniciated by heating and Ehrenfests classification of phase transitionsFor a long time, transmutations, metamorphoses, and changes of substances (of fluid and solid bodies) have been the original subject of any investigation of alchemists as well as of more recent...
Ehrenfest classification of phase transitions discerns between two categories: first-order transitions obeying Clapeyron equation and second-order transitions that should obey Ehrenfest equations. Considering the equilibrium phase diagram of binary systems with lentiform two-phase field and with bell-shaped ...
We discuss the consequences of a third-order phase transition in the Ehrenfest classification. We also discuss the applicability of these ideas to transitions in Bi-based superconductors.doi:10.1016/0921-4526(94)91852-XP. KumarPhysica B Condensed Matter...
A translation of Paul Ehrenfest's 1933 paper, entitled Phase transitions in the usual and generalized sense, classified according to the singularities of the thermodynamic potential is presented. Some historical commentary about the paper's context is also given....
