Abstract: Abstract We used two different solid state synthesis routes in conjunction with Current Activated Pressure Assisted Densification (CAPAD) to produce lead-free 0.5Ba(Zr0.2Ti0.8)O3–0.5(Ba0.7Ca0.3)TiO3 (called BZT-BCT or BXT) ceramics. The materials are fully dense and have a… read more here.

Abstract: ABSTRACT Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 (BZT-xBCT) is a promising lead-free ferroelectric system with high piezoelectricity. Here we carry out phenomenological calculations to explore phase stability and electric field induced phase transition. Study of free energy variation near phase… read more here.
