Direct measurements of the specific volume of deuterium oxide (D2O) solutions were made with a magnetic float densimeter from 2° to 40°C and from 0 to 1000 bars applied pressure. The results were fitted to a second degree secant bulk modulus equation: (V0P)/(V0 – VP) = A0+ A1P + A2P2+ CP2- where V0 and VP are the specific volumes at zero and P applied pressure, A0= 1/β0 the reciprocal of the 1 atm compressibilities, and A1 and A2 are temperature dependent parameters. The specific volumes were fitted to this equation with a standard deviation of 6 ppm over the entire pressure and temperature range. The equation of state of D2O was used to compute several thermodynamic properties that are compared to the results obtained by other workers from 5° to 40°C and 0 to 1000 bars.
