Phase diagram thermodynamic calculation

Kaufman and Bernstein (1970) brought out the first book on phase diagram calculations there was not another comprehensive treatment till Saunders and Miodownik s book came out in 1998. This last covers the ways of obtaining the thermodynamic input data, ways of dealing with complications such as atomic... 

At what temperature and density does the phase transition to quark matter occur To determine the phase diagram of thermodynamic QCD is an outstanding problem. The phases of matter are being mapped out by colliding heavy-ions and by observing compact stars. Since QCD has only one intrinsic scale, Aqcd> the phase transition of QCD matter should occur at that scale as matter is heated up or squeezed down. Indeed, recent lattice QCD calculations... 

A significant review of several aspects of the phase diagram computation (phase diagram calculations in teaching, research and industry) has been published by Chang (2006). The relationship between the characteristic features of a phase diagram and the relative thermodynamic stabilities of the phases involved has been there underlined and exemplified. Representative examples of binary, ternary and high-order alloy systems have been presented. Moreover a number of applications have... 

Pandat software package and applications (Chen et al. 1993). Pandat is a software package for multi-component phase diagram calculations. Given a set of thermodynamic parameters for all phases in a system and a set of user constraints, Pandat automatically calculates the stable phase diagram without... 

A phase diagram is often considered as something which can only be measured directly. For example, if the solubility limit of a phase needs to be known, some physical method such as microscopy would be used to observe the formation of the second phase. However, it can also be argued that if the thermodynamic properties of a system could be properly measured this would also define the solubility limit of the phase. The previous sections have discussed in detail unary, single-phase systems and the quantities which are inherent in that sjrstem, such as enthalpy, activity, entropy, etc. This section will deal with what happens when there are various equilibria between different phases and includes a preliminary description of phase-diagram calculations. 

In this chapter we show a large part of the experimental phase diagram and thermodynamic data for the Ga-In-Sb and Hg-Cd-Te systems along with calculated values for these data obtained from a simultaneous, quantita-... 

Figure 16 shows the gas-liquid phase diagrams calculated with DHH+ DHHDS [65, 81], compared to the ones calculated from MSA and from BB+ODS. Also include the data of Loth et al. [102] and those obtained from the Gibbs ensemble method by Panagiotopoulos [103]. Note that the reported values obtained from DHH+DHHDS are only estimates, because as said above, this approximation, even if accurate, exhibits little thermodynamic inconsistencies. As...

Fig. 2.37. Phase diagram for Ca0-Na20 Si02-(Al203)-H20 system in equilibrium with quartz at 400°C and 400 bars. Plagioclase solid solution can be represented by the albite and anorthite fields, whereas epidote is represented by clinozoisite. Note that the clinozoisite field is adjacent to the anorthite field, suggesting that fluids with high Ca/(H+) might equilibrate with excess anorthite by replacing it with epidote. The location of the albite-anorthite-epidote equilibrium point is a function of epidote and plagioclase composition and depends on the model used for calculation of the thermodynamic properties of aqueous cations (Berndt et al., 1989).
