Phase formation and characterization of (1-x)PZT-xBNbT ceramics
This present study aims to fabricate and characterize a series of new complex-structured ceramics with formula (1-x)Pb(Zr0.52Ti0.48)O3-xBi3.99Ti2. 97Nb0.03O12 or (1-x)PZT -xBNbT (when x 0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0) using a solid-state mixed oxide method and sintered at temperatures in between...
