Environmental concerns are strongly driving the need to replace the lead-based piezoelectric materials currently employed as multilayer actuators. The current review describes both compositional and s...
The impurities sulphur, phosphorus, lead, bismuth, tin and antimony affect the hot workability of stainless steels. In this study we show that lead segregate to phase and solidification-grain boundar...
Lead-free piezoelectric ceramics (1−x)(Na0.5K0.5)NbO3-xBiFeO3 (x = 0  0.07) were synthesized by the solid-state reaction. Differential scanning calorimetry (DSC) measurements revealed that an...
