The BCZT ceramic derived from the MSGH-synthesized powders had a dense structure (density 5.57 g/cm 3) as well as excellent electrical properties (ε m = 9579, d 33 = 496 pC/N, 2P r = 25.22 µC/cm 2, E c = 7.52 kV/cm), which was attributed to the high activity of the powders rapidly synthesized by MSGH.
