Beschreibung
Zusammenfassung:	Bi4Ti3O12 (BIT), (Bi3.2Nd0.8)Ti3O12 (BNT), (Bi3.2Nd0.8)(Ti2.95Nb0.05)O12 (BNTN) and (Bi3.2 Nd0.8)(Ti2.95V0.05)O12 (BNTV) ceramics were prepared by using a solid state reaction method. The effects of Nd/Nb and Nd/V co-doping on the dielectric, ferroelectric and electrical properties were studied. Nd/Nb and Nd/V co-doping decreased the low-frequency dielectric dispersion and the electrical conductivity. The BNTN and the BNTV ceramics exhibited saturated P-E hysteresis loops and the corresponding remanent polarization increased. The Nd/Nb and Nd/V co-doping of BIT decreased its conductivity and improved its ferroelectric properties. KCI Citation Count: 6
