A polycrystalline orthorhombic compound of Li0.5Bi0.5Ti0.8Zr0.2O3 is synthesized by using a high temperature solid-state reaction technique at
high temperature (i.e., at 900℃).
The room temperature X-ray diffraction study assured the evolution of
single-phase compound with orthorhombic structure. The dielectric analysis of
Li0.5Bi0.5Ti0.95Zr0.05O3 explored over a broad frequency range (103 - 106 Hz) at various temperatures (33℃ - 500℃) displayed that the dielectric properties of
the material are dependent on both frequency and temperature. Dielectric study
reveals that the ferro to paraelectric phase transition of the studied compound
is a temperature of 112℃.
The nature of the variation of conductivity and value of activation energy in
different regions, calculated from the temperature dependence of ac
conductivity suggest that the conduction process is of mixed type (i.e., ionic–polaronic and space charge
generated from the oxygen ion vacancies).
