Abstract:
Phase relation of the systems [Pb 1- y (Na 1/2 Bi 1/2 ) y ](Ti 1- x Zr x )O 3 and [Pb 1- y (K 1/2 Bi 1/2 ) y ](Ti 1- x B x )O 3 with B=Zr, Fe 1/2 Nb 1/2 , Zn 1/3 Nb 2/3 , Mg 1/3 Nb 2/3 or Mg 1/2 W 1/2 have been investigated. With increasing x and y , T C decreased and peaks in ε - T curves became broader. Phase diagrams of all the systems at room temperature were determined. As the concentration y of Na 1/2 Bi 1/2 or K 1/2 Bi 1/2 was increased, the tetragonal-to-rhombohedral boundary shifted to smaller x and the tetragonal phase was suppressed within x ∼0.1 on the ( K 1/2 Bi 1/2 ) side. Piezoelectric response was examined in ceramic specimens with composition in the vicinity of the boundary in all systems, and a value of 0.18 as K (= C 1 / C 0 ) was found in the [Pb-(K 1/2 Bi 1/2 )](Ti-Zr)O 3 system.
