Abstract: Relaxor ferroelectric lead scandium niobate Pb$_2$ScNbO$_6$ (PSN) ceramics was obtained by solidstate synthesis and a modified ceramic technology, whereby the sintering stage was preceded by room-temperature compression and shear straining of the synthesized PSN powder in Bridgman anvils. It is established that this mechanical activation leads to the development of dynamic recrystallization processes in PSN grains, which significantly influence the physical properties of the final ferroelectric ceramic material.
