- Аннотация: Influence of doping elements Li, Mg, Sr, Mn on synthesis conditions, and sinterability, and electrophysical properties of lead-free (K0.5Na0.5)Nb03 based piezoelectric ceramics is studied. The effects revealed are correlated well with the adopted concepts of soft and hard doping elements for ferroelectric substances. On the base of the it is obtained A lead free piezoelectric ceramics with the Curie point Tc =410°C has been obtained based on manganese modified (K0.5Na0.5)NbO3 solid solution. The piezoelectric constant d33 of the said ceramics exceeds the well-known analogs and the piezoelectric sensitivity gg33 exceeds almost 4 times that of the best lead zirconate-titanate based ceramics. © 2010 - STC ”Institute for Single Crystals”.
