Structural, dielectric and electrical properties of bismuth magnesium tantalate electronic system

The lead-free dielectric compound Bi(Mg2/3Ta1/3)O3 (BMT) has been synthesized at high temperature by a low-cost solid-state method. The X-ray diffraction (XRD) technique reveals that the fabricated sample has an orthorhombic crystal system. The scanning electron microscope (SEM) image displays the uniform distribution of grains on the surface of the specimen. The dielectric parameters (permittivity (εr), and loss tangent (tan δ) are studied over...
