Thermophysical Properties Variables
The Thermo‑Calc databases have a variety of properties data included such as molar volume, thermal conductivity, dynamic and kinematic viscosity, thermal resistivity, electrical resistivity, and surface tension. These properties data are being integrated into databases as each new version of a database is released.
Availability of properties data is dependent on both the database and its version. Some information is specific to use in Console Mode. There is more information also available for Graphical Mode, TC‑Python, or TC-Toolbox for MATLAB® for each of the databases where the properties data is included. More advanced information is also contained in the Database Manager User Guide PARAMETER section.
To determine if the database you are using has this properties data, search the help (press F1) to review the technical information. The availability of properties data is also included with the Database Overview document available on the Thermo‑Calc website.
