In the present work the phase P — T diagram of ice is constructed in the temperature range 90–250 K and is ascertained at temperatures 250–300 K and pressures up to 2500 MPa. A new modification of ice — ice XII — was found. Compressibility and Grüneisen coefficients for a number of ice modifications were determined.
