	<span style="line-height:1.5;">A polycrystalline orthorhombic compound of </span><span style="line-height:1.5;">Li</span><sub>0.5</sub><span style="line-height:1.5;">Bi</span><sub>0.5</sub><span style="line-height:1.5;">Ti</span><sub>0.8</sub><span style="line-height:1.5;">Zr</span><sub>0.2</sub><span style="line-height:1.5;">O</span><sub>3</sub><span style="line-height:1.5;"> is synthesized by using a high temperature solid-state reaction technique at
high temperature (</span><i style="line-height:1.5;">i.e.</i><span style="line-height:1.5;">, at 900¡æ).
The room temperature X-ray diffraction study assured the evolution of
single-phase compound with orthorhombic structure. The dielectric analysis of
Li</span><sub>0.5</sub><span style="line-height:1.5;">Bi</span><sub>0.5</sub><span style="line-height:1.5;">Ti</span><sub>0.95</sub><span style="line-height:1.5;">Zr</span><sub>0.05</sub><span style="line-height:1.5;">O</span><sub>3</sub><span style="line-height:1.5;"> explored over a broad frequency range (10</span><sup>3</sup><span style="line-height:1.5;"> - 10</span><sup>6</sup><span style="line-height:1.5;"> Hz) at vari</span><span style="line-height:1.5;">ous temperatures (33¡æ - 500¡æ) 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¡æ.
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 (</span><i style="line-height:1.5;">i.e.</i><span style="line-height:1.5;">, ionic¨Cpolaronic and space charge
generated from the oxygen ion vacancies).</span>
