Dear community,
I am searching for physical properties data for argon gas such as dynamic viscosity, specific heat capacity, density and thermal conductivity. I am aware about the NIST thermophysical database. The database does provide thermophysical properties until 1500 K and 2000 K for helium and nitrogen, respectively. In case of argon, the data are limited to 700 K. I do need data for temperatures up to 1500 K, but I am not able to find anything. Does anyone know if this data exists? If so, how can I find the data? Indeed, it is possible to extrapolate the data, but real data is prefered.
Thanking you in advance!

Is the following literature position helpful?

Have you checked the CRC handbook of chemistry and physics?
Thanks

Did you already look into the VDI Heat Atlas? There's a specific isobaric heat capacity diagram showing minimal to 0 changes on argon's cp till 2000 °C
The internal energy of real gas includes kinetic energy and potential energy. It is assumed that kinetic energy is only concerned with temperature and is independent of volume and density. In gravitational field, real gas obey static equilibrium and convection balance. The two equations contain gravity, molecular potential energy and equation of state. The two equations are combined to remove gravity, and the relationship between the equation of state and potential energy is obtained. According to the relation, this paper calculates the specific heat of HFC125, sound velocity virial coefficients of R143a, HFC227ea from the state equation. The three results are in accordance with the experiment.
