Thermophysical Parameters and Variables

Below is a summary of the available thermophysical parameters and variables for the databases when working in Thermo‑Calc. There are differences when you are working in Console Mode versus Graphical Mode as well as if you use an SDK such as TC‑Python or TC-Toolbox for MATLAB®.

Property (and Graphical Mode Variable Name)	Model Parameters	Variables to Show or Plot in Console Mode or the SDKs (TC‑Python, or TC-Toolbox for MATLAB®)***
Molar volume	V0, VA	VM for a system VM(PHI) for phase PHI
Electrical conductivity	ELQ**	ELCD for a system ELCD(PHI) for phase PHI
Electrical resistivity	ELRS, ESPD	ELRS for a system ELRS(PHI) for a phase PHI
Thermal conductivity	THCD	THCD for a system THCD(PHI) for phase PHI
Thermal resistivity		THRS for a system THRS(PHI) for phase PHI
Thermal diffusivity		THDF for a system THDF(PHI) for phase PHI
Surface tension	SIGM, XI*	SURF(LIQUID) SURF(ION)**
Dynamic viscosity	VISC	DVIS(LIQUID) DVIS(ION)**
Kinematic viscosity		KVIS(LIQUID) KVIS(ION)**
* XI is not used in the TCOX database (all versions). As of 2023b it is also not used starting with the following versions of these databases: TCFE13, TCNI12.1, TCTI5.1, TCNOBL3, TCPMAG2, and TCCU6. As of 2024a, TCMG7, TCAL9, and TCHEA7. As of 2024b, TCSLD5. ** ION is used in the TCS Metal Oxide Solutions Database (TCOX) *** The examples listed for the SDKs are using Console Mode syntax. The quantities can also be accessed in both ThermodynamicQuantity and ScheilQuantity classes. See the various model descriptions or the SDK help for details.
