Abstract Scope |
Morphotropic phase boundary (MPB) and polymorphic phase boundary (PPB) have been widely used for relaxor ferroelectric materials innovation and lead to the finding of the typical relaxor PMN-PT which has various advanced applications but contain harmful element Pb to the environment. Dipole engineering in BaTiO3 material help create a new type of Pb-free ferroelectric relaxor that is different from the classic relaxor. In this work, we report a unique relaxor based on dipole-pair substituted [Zn, W]: BaTiO3 ceramics. Investigation of crystal structure, microstructure, and electric, dielectric and optical properties has been performed and the dipole-pair concentration-dependent relative permittivity is discussed. [Zn, W]: BaTiO3 ceramics could benefit some electronic applications that require Pb-free relaxors. |
