摘要：
We have examined the effect of preparation conditions on the structure and piezoelectric characteristics of ceramic samples in the form of thin piezoelectric disks cut from large sintered (1 − x)BiScO3 - xPbTiO3 (x = 0.635–0.645) bodies. The use of chemical coprecipitation from nitrate solutions allowed us to prepare nanopowders of controlled composition and ensured better piezoelectric activity of the materials in comparison with ceramics produced by solid-state reactions. We discuss possible ways of optimizing functional parameters of piezoelectric elements from BSPT ceramics.
