• Ammonia
• High temperature
• High pressure

An analytical equation of state is presented for ammonia to describe its thermodynamic properties over wide ranges of temperatures and pressures up to 3000 K and 20 GPa, respectively. The equation of state contains well-defined parameters, two of which have been slightly adjusted around their global values based on a limited set of experimental data. The properties of ammonia predicted by the new equation of state are in very good agreement with the experimental data and the first-principles molecular dynamics simulation results over a broad range of temperatures and pressures. The new equation of state is expected to supplement molecular simulations at conditions where experimental data are not yet available.
