Abstract:
Pb free Ba(Ti0.8Zr0.2)O3-x(Ba0.7Ca0.3)TiO3 with Morphotropic Phase Boundary, MPB composition has excellent piezo and ferroelectric properties, therefore it has received extensive attention as its potential application. In this paper, the film with MPB composition was fabricated by sol gel method and single crystal was also tried by floatingzone method. The phase was confirmed by XRD, and surface morphology was characterized by AFM. The electric hysteresis loop was measured by TFAnalyzer2000HS. Finally, we analyzed the influence of growth atmosphere on the crystal quality and ultraviolet visible transmittance spectrum.
