The influence of BaTiO3 nanocrystals on the electrical characteristics and energy storage capabilities of BNKT ceramics
Source abstract
Abstract
This study demonstrates that the incorporation of BaTiO 3 (BT) nanocrystals improved the electrical characteristics of lead-free Bi 0.5 (Na 0.4 K 0.1 ) 0.5 TiO 3 (BNKT) ceramic. The molten-salt technique was employed to produce nanocrystal seed. 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 5.82-5.88 g/cm 3 , with a theoretical density of 97-98%. A doping BT seed concentration of 0.02 yielded an optimum density value of 5.88 g/cm 3 and a dielectric constant of around 1566. The highest ε r 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 (%S max ), and strain coefficient (d* 33 ) of 0.57 J/cm 3 , 67.13%, 0.21%, and 351.67 pm/V, respectively.
