Item The Effect Of Addition Of Nd3 + On Dielectric Properties Of Pb[zr0.45ti0.45(zn1/3, Sb2/3)0.1]o3 System(University of Eloued جامعة الوادي, 2011-07-01) Abdessalem, N.; Boutarfaia, A.; Abba, M.; Necira, Z.This work aims at, to study the influence of Nd3+ on the dielectric properties of a ceramics material of general formula: Pb[Zr0.45 Ti0.45 (Zn1/3, Sb2/3) 0.1]O3 and of structure perovskite. The selected samples were prepared by the method of synthesis with solid way. The study of the dielectric properties of the system showed that the values of the permittivity, the resistivity, increase with the addition of Nd+3 1%.Item Elaboration And Dielectric Characterization Of A Doped Ferroelectric Material Type Pzt(University of Eloued جامعة الوادي, 2013-07-01) Abba, M.; Necira, Z.; Abdessalem, N.; Meklid, A.; Menasra, H.; Boutarfaia, A.The main objective of this work is based on the synthesis and dielectric characterization of a new material in ceramic PZT with a perovskite structure ABO3.We are interested to study the Quaternary system (doping in site A and site B) of general formula:Pb0.96Ba0.02Ca0.02[(Zr0.52Ti0.48)0.94(Zn1/3Ta2/3)0.03(In1/3Sb2/3)0.03]O3 short PZT-PBC-ZTIS.The sample selected for this study was prepared by the method of synthesis with solid way. Heat treatment was applied to these compositions at different temperatures: 1100, 1150,1180 and 1200 °C successively to optimize the sintering temperature optimal where the density of the sample is maximum (near theoretical density) and therefore the product has better physical quality.The study of dielectric properties of all samples showed a high permittivity dielectric εr = 18018, low dielectric loss: tgδ = 7.62%, for the composition sintered to 1180 ° C included in the phase morphotropique zone (FMP).
