In order to solve the low temperature stability of electrical properties in KNN-based ceramics, (1−x)[(K 0.5 Na 0.5 ) 0.95 Li 0.05 ](Nb 0.95 Sb 0.05 )O 3 –xBaTiO 3 [(1−x)KNLNS–xBT] lead-free piezoelectric ceramics were prepared by the conventional solid-state sintering method. The introduction of BT stabilizes the tetragonal phase of...
In order to shift the tricritical point to room temperature, Ba 0.85 Ca 0.15 Ti 0.90 Zr 0.10 O 3 (BCTZ) ceramics were prepared by normal sintering with the addition of ZnO. The sintering behavior of BCTZ ceramics is also improved by using ZnO as a sintering aid. The room-temperature tricritical point results in improved electrical properties of ZnO-modified...
