Structural, microstructural, and electrical behavior of a relaxor (Mg0.5W0.5)(Pb0.5Ni0.5)O3 electronic material

The perovskite solid solution (Mg0.5W0.5)(Pb0.5Ni0.5)O-3, or MWPN, is synthesized for this study utilizing a solid-state reaction technique. The material's structure, shape, and electrical properties have been meticulously investigated and documented in order to get a better knowledge of its possible uses in electronic devices and sensors. Using X-ray diffraction investigations, we were able to conclude that the structure is tetragonal (space group 141/a(88), z = 4). Dielectric property, impedance spectroscopy, and alternating current conductivity tests have been performed over a wide range of temperatures and frequencies (ranging from 25 & DEG;C through 500 & DEG;C for temperatures and from 10 kHz to 1 MHz for frequencies). The appearance of a single semicircular arc in the Nyquist analysis findings suggests that the sample in issue is made up of grains. An analog model of an equivalent circuit has been built in order to analyze the electrical functioning. The activation energy for different frequency has been calculated. Methodical study is carried out on the dielectric properties of the material when it is exposed to high temperatures in order to explore the electrical differences that occur between surfaces, grain boundaries, or grains in a material. Relaxor behavior of the sample has been revealed. This is required for both the basic characterization and the construction of devices.
