This chapter discusses phase, which is a form of gas, liquid, solid, or supercritical fluid which is uniform in its chemical composition and its physical state. The chapter emphasizes that 'vapour' is used to describe the gaseous phase of substances which are liquids or solids at room temperature.

Phase equilibrium and phase diagrams
2011A phase diagram is a graph that shows the distribution of stable phase assemblages as a function of the values of the intensive variables used to describe the thermodynamic system. If pressure and temperature are the variables of interest then the stable assemblage is the one with the lowest Gibbs free energy, although other thermodynamic potentials ...

Abstract This chapter aims to develop the fundamental equations of thermodynamics which govern equilibrium between reacting species or phases. It begins with a review of the basic thermodynamic state variables of a homogeneous phase, followed by a discussion of the basic concepts of phase equilibrium in pure species as well as in multi ...

Phase Equilibrium and Phase Diagram
2019Phase equilibrium and phase diagram advise us what is the stable substance under certain circumstances and what condition is needed for the stability of the substance. This chapter describes the fundamental to understand the phase equilibrium and the phase diagram: the phase rule, the phase transformation with the change in the temperature or the ...

Calculations of order—disorder phase transformations reduce to determining and comparing the free energies of disordered and various ordered phases. Consequently, it is possible to find temperature and concentration intervals within which one or another phase is in a thermodynamic equilibrium state.

As many ceramics are oxides, the oxygen partial pressure, pO2, is an important variable. There is a lot of information about many metal–oxygen systems. In part, this is due to interest in how to obtain metals by direct reduction from their oxides. A frequent way of representing free energies of formation of oxides as a function of pO2 and T is the ...
