Toughening of PZT ceramics by In-situ complex structures
This research fabricated ceramics with formula (l-x)PZT - xBLT, when x = 0, 0.03, 0.05, 0.07, 0.10, 0.15 and 0.20 by a solid-state reaction method and sintered at a temperature of 1150 °C for 4 h with a heating/cooling rate of 5 °Cmin-1. Phase analysis using XRD indicated the existence of PZT-based...
