Abstract

Fine powders of orthorhombic bismuth vandate (Bi2VO5.5) have been synthesized by coprecipitation method. Powder X-ray diffraction and electron microscopic techniques have been used to characterize these samples. The formation of the monophasic Bi2VO5.5 was confirmed. The compacted powders sintered at 1070 K have been characterized for their dielectric properties as a function of both temperature (300-900 K) and frequency (100 Hz-10 MHz) and found to be superior to those obtained by the conventional solid-state reaction route.
