Calphad modeling of molar volume and isothermal compressibility has become a topic of interest in recent years. A few proprietary databases now include descriptions of molar volume for each of the phases; though descriptions of temperature/pressure-dependent molar volume in computational thermodynamics is still quite a new idea. As a result, several different Calphad-type models for temperature/pressure-dependence have been proposed and used in recent literature. This work provides a comprehensive narrative of these models; including how some were derived, their advantages, shortcomings, and the challenges that arise when different models are merged in a multicomponent description. The goals are to offer new researchers to the field a single source to which to refer regarding the subject; and to open a dialogue in the community to discuss reaching a consensus on what model descriptions should be used as standards in future endeavors.
