A Superparaelectric State in Relaxor Ferroelectric (Sr,Bi)TiO-Bi(Mg,Ti)O-Modified BaTiO Ceramics to Achieve High Energy Storage Performance.

Dielectric ceramic capacitors are highly regarded for their rapid charge-discharge, high power density, and cyclability in various advanced applications. However, their relatively low energy storage density has prompted intensive research aiming at developing materials with a higher energy density. To enhance energy storage properties, research has focused on modifying ferroelectric materials to induce relaxor ferroelectricity.

Grain Growth Behavior and Electrical Properties of 0.96(KNa)NbSbO-0.04Bi(NaK)ZrO Ceramics.

This study investigated the causes of microstructural changes and the resultant electrical properties according to the sintering temperature of 0.96(KNa)NbSbO-0.04Bi(NaK)ZrO lead-free ceramics by analyzing the correlation between vacancy concentrations and 2D nucleation.
