[en] These tables display the thermodynamic properties of 100% D₂O over the complete range of single phase states between the triple point temperature and 800⁰C and from ideal gas pressures up to 100 MPa. The tables are based on a new equation of state which is continuous over the entire range of states. The equation is in the form of a Helmholtz free energy function of density and temperature and has been formulated after a comprehensive review of available data. The properties of the saturated states are presented both as functions of temperature and as functions of pressure, as well as entropy and pressure, and enthalpy and pressure. The critical region is the subject of a special table as is the ideal gas
