| Abstract: | The use of lead free materials in piezoelectric ceramics has recently become a very important issue in environment protection. The research in bismuth layer structure ferroelectrics and the piezoelectric properties of Na0.5 Bi0.5 TiO3 based materials are reviewed. The effecting mechanism of additives on piezoelectric properties of these materials is introduced. The optimization in microstructure and piezoelectric properties by new process are discussed. It is noted that these materials are potential candidates as lead free piezoelectric ceramics. |
