Properties of the ferroelectric ceramics PbSc0.5Ta0.5O3 fabricated from an ultradispersed powder

The relaxor ceramics PbSc 0.5 Ta 0.5 O 3 produced from an ultradispersed powder is studied by X-ray diffraction and dielectric measurements. Before sintering, the powder was subjected to treatment in Bridgman anvils in combination with shear deformation. This method is shown to affect the order para...

Beschreibung
Zusammenfassung:	The relaxor ceramics PbSc 0.5 Ta 0.5 O 3 produced from an ultradispersed powder is studied by X-ray diffraction and dielectric measurements. Before sintering, the powder was subjected to treatment in Bridgman anvils in combination with shear deformation. This method is shown to affect the order parameter and dielectric properties of the ceramics without using long-term high-temperature annealing.
