The influence of BaTiO3 nanocrystals on the electrical characteristics and energy storage capabilities of BNKT ceramics
This study demonstrates that the incorporation of BaTiO3 (BT) nanocrystals improved the electrical characteristics of lead-free Bi0.5(Na0.4K0.1)0.5TiO3 (BNKT) ceramic. The molten-salt technique was employed to produce nanocrystal seeds. Upon mixing BNKT with BT nanocrystal seeds, the phase structure exhibited a combination of rhombohedral and tetragonal phases. The ceramics exhibit bulk density values ranging from 5.82 to 5.88 g/cm3, with a theoretical density of 97–98 %. A doping BT seed concentration of 0.02 yielded an optimum density value of 5.88 g/cm3 and a dielectric constant of around 1566. The highest εr value is 4575 for the sample containing a BT seed of 0.06 mol. The incorporation of BT seed = 0.02 resulted in optimal energy storage density (W), energy efficiency (η), maximum strain (%Smax), and strain coefficient (d∗33) of 0.57 J/cm3, 67.13 %, 0.21 %, and 351.67 pm/V, respectively.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
