## Abstract The hydrostatic pressureβinduced ferroelectric to antiferroelectric (FEβAFE) phase transformation of PZT95/5 ceramics was investigated as a function of porosity, pore shape and pore size. FEβAFE phase transformations were more diffuse and occurred at lower hydrostatic pressures with inc
The hydrostatic pressure-induced martensitic transformation from the ferroelectric rhombohedral to antiferroelectric orthorhombic phase in PZT 95/5 ceramics has been studied using neutron diffraction. The transition to the orthorhombic phase initiates at a pressure of 260 MPa and is almost complete
