At TSCC by hydrostatic pressure a shifting of phase transition to higher temperatures was observed. The initial shifting is dTo/dp = 0.097 K/MPa for a monodomain and dTo/dp = 0.125 K/MPa for a multidomain TSCC-crystal. At pressures higher than 300 MPa a nonlinear shifting was found. Above pressures of 420 MPa no phase transition could be detected by dielectric measurments.
