	<span style="line-height:1.5;">Ba</span><sub>5</sub><span style="line-height:1.5;">SmZr</span><sub>3</sub><span style="line-height:1.5;">V</span><sub>7</sub><span style="line-height:1.5;">O</span><sub>30</sub><span style="line-height:1.5;"> is a new tungsten bronze structured ceramic compound prepared by substituting Zr at Ti site in Ba</span><sub>5</sub><span style="line-height:1.5;">GdTi</span><sub>3</sub><span style="line-height:1.5;">V</span><sub>7</sub><span style="line-height:1.5;">O</span><sub>30</sub><span style="line-height:1.5;"> following high-temperature solid-state reaction route. The X-ray diffraction analysis of the compound confirms
the formation of single-phase orthorhombic structures at room temperature.
Surface morphology of the compound was studied by scanning electron microscopy.
Using a Hioki LCR meter, the effects of
temperature (32¡æ - 500¡æ) and frequency (10</span><sup>2</sup><span style="line-height:1.5;"> - 10</span><sup>6</sup><span style="line-height:1.5;"> Hz) on structural and electrical
properties were studied. Detailed analysis of impedance parameters furnishes a </span><span style="line-height:1.5;">better conception of the electrical properties and type of relaxation processes
in the material. The plateau region of the Z</span><i style="line-height:1.5;">¡¯</i><span style="line-height:1.5;">~ frequency plot also indicates the presence of
relaxation process in the material. The bulk resistance is observed to be
decreased with rise in temperature showing a typical negative temperature
coefficient of resistance (NTCR) behavior.</span>
