摘要：

DTA and dielectric measurements have been applied to study the pressure and temperature dependence of the phase transitions of 1,3-cyclohexanedione crystals. The measurements were performed up to 180 MPa and between 270 and 400 K. The obtained P-T phase diagram indicates a strong positive and linear pressure dependence of the temperature of the transition between two phases of the same space group symmetry, P2(1)/c. The mechanism of the phase transition is discussed.
