Abstract
Bismuth strontium titanate (Bi(Sr0.5Ti0.5)O3) compound is prepared by a solid state reaction technique. It has been characterized by means of different experimental procedures. Investigation regarding crystal structure via X-ray diffraction records has revealed the orthorhombic crystal structure of the material. The quality of the sample was asserted by studying its microstructure and morphology. Detailed investigations of dielectric and electrical properties of Bi(Sr0.5Ti0.5)O3 in a broad frequency (100 Hz–1 MHz) and temperature (25–500 °C) ranges have offered various exciting results of anti-ferroelectric behavior, conduction mechanism etc. The existence of Maxwell–Wagner dielectric relaxation and space charge polarization at lower frequencies and higher temperatures in the material has been observed. The analysis of Nyquist graphs confirmed the temperature-dependent grain and grain boundary effects. The transport properties and ac conductivity of the material, which are strongly affected by the temperature and frequency of the applied electric field, have been studied.
