Enhanced energy storage performance in reaction-sintered AgNbO antiferroelectric ceramics.

In this research, AgNbO ceramics were produced by two sintering methods: reaction sintering (RS) and conventional solid-state sintering (CSSS). The process was similar for both methods, except that in RS, AgO and NbO precursors were mixed, then formed into pellets, skipping the calcination step, and sintered at 1100 °C for 6 hours. Both prepared ceramics had the same perovskite crystal structure with an orthorhombic crystal system and and 2 space groups with similar lattice dynamic vibration modes at room temperature.
