DOI: 10.1111/jace.14887
Abstract: In this study lead‐free 2‐2 and 0‐3 ceramic/ceramic composites comprised of the non‐ergodic relaxor 0.93(Bi1/2Na1/2)TiO3–0.07BaTiO3 and ergodic relaxor 0.94Bi0.5(Na0.75K0.25)0.5TiO3–0.06BiAlO3 were investigated. The macroscopic electromechanical behavior was characterized as a function of continuent content, revealing an… read more here.
