Abstract
PZT95/5 samples were prepared with the conventional ceramic process. Based on the principle of the same valance, different ionic radius; similar ionic radius, different valances, the additives such as alkali-metal carbonates, alkali-earth-metal carbonates, Fe203, SiO2, Nb2O5 and WO3 were doped into the PZT95/5 separately. The dielectric properties, polarization properties and FRL-FRH phase transition behavior were studied. The acceptor additives make the dielectric constant of the material decrease, and the donor additives demonstrate the opposite effect; The remnant polarization in the material is enhanced with the increase of the cationic valances of additives; The pure PZT95/5 ferroelectric material obtained with the FRL-FRH phase transition temperature of 15°C, which is significant for its application.
