Dielectric properties and dielectric aging of 0.9Pb(Mg1/3Nb2/3)O3-0.1PbTiO3 doped with CaO
The relaxor ferroelectric, 0.9Pb(Mg1/3,Nb2/3)O3-0.1PbTiO3 (0.9PMN-0.1PT) doped with different concentrations of CaO, was studied. Doping with CaO can increase the grain size. The maximum value of dielectric constant decreased and the degree of diffuse phase transition (DPT) was enhanced with CaO dop...

Summary: | The relaxor ferroelectric, 0.9Pb(Mg1/3,Nb2/3)O3-0.1PbTiO3 (0.9PMN-0.1PT) doped with different concentrations of CaO, was studied. Doping with CaO can increase the grain size. The maximum value of dielectric constant decreased and the degree of diffuse phase transition (DPT) was enhanced with CaO doping. Also, obvious ageing effects were found. Analysis shows that Ca2+ ions enter the lattice partly substituting the Nb5+ or Ti4+ ions at B-sites. 23 refs. |
