摘要：

The polycrystalline bismuth strontium ferric titanate (Bi(Sr0.25Ti0.25Fe0.5)O-3), synthesized via a high-temperature solid-state reaction route, has been characterized by using different experimental procedures. Study of basic crystal structure with the help of X-ray diffraction data of the compound exhibits the rhombohedral crystal system. The quality of the sample was asserted by studying its microstructure and morphology. Detailed investigations of dielectric and electrical properties of Bi(Sr0.25Ti0.25Fe0.5)O-3 in a broad frequency (1 kHz-1 MHz) and temperature (25-450 degrees C) ranges have provided various important information on conduction mechanism, structure-properties correlationship, etc. The high dielectric constant and relativly low tangent loss with multiple phase transitions have been observed in the material I the experimental frequency and temperature ranges.
