Characterization and production of multilayer lead free piezoelectric ceramics

In recent years, studies on "NBT-BT" piezoelectric ceramics, which are used as an alternative to "PZT" ceramics have increased. Although PZT ceramics are preferred in many areas due to their characteristics and high performance, their use in terms of human and environmental health is restricted in many countries. NBT-BT compositions are preferred in various applications and investigations because of the morphological phase boundary and the ability to increase the specificity of various additives. In this study, the changes of electrical properties of the materials (94Bi0.5Na0.5TiO3-6BaTiO3) (94NBT-6BT) synthesized in different grain size range and different temperatures were investigated depending on Mangan contribution. After the studies on pellets, multi-layer NBT-BT compositions were synthesized and ceramics were produced by tape casting method and electrical properties and fatigue behavior are investigated.
