Size effect on structure and dielectric properties of Nb-doped barium titanate
(Elsevier B.V., 2003-12-20)
It is known that the dielectric properties of BaTiO3 (BT) are strongly dependent on its grain size. Coarse-grained ceramics of pure BT showed lower dielectric constant at room temperature then fine grained. Many authors ...
In Vitro Cytotoxicity of a Ti-35Nb-7Zr-5Ta Alloy Doped with Different Oxygen Contents
(Mdpi Ag, 2014-03-01)
Cp-Ti is the most common material used for dental implants, but its elastic modulus is around five times higher than that of bone. Recently, promising alloys that add Nb, Ta, Zr and Mo to Ti have been developed. The ...

Phase analysis of seeded and doped PbMg1/3Nb2/3O3 prepared by organic solution of citrates
(1996-07-01)
PbMg1/3Nb2/3O3 (PMN) prepared by organic solution of citrates was analyzed by the Rietveld method to determine the influence of seeds and dopants on the perovskite and pyrochlore phase formation. It was observed that ...

Doping effect on the physical properties of bi-layered aurivillius-type structure SrBi2Nb2O9 ferroelectric ceramics: SrBi2Nb2O9 (SBN) aurivillius-type ferroelectric ceramics
(2014-10-13)
The doping effect on the structural, microstructural and dielectric properties of bismuth layer structured SrBi2Nb2O9(SBN) ferroelectric ceramics has been investigated. The samples were obtained from the solid state reaction ...
Influence of Nb doping on magnetic properties of nanocrystalline Nd-Fe-B alloys
(Institute Of Electrical And Electronics Engineers, 2013-07)
The influence of Nb doping was studied on ribbons of nominal composition NdyFe86-x-yB14Nbx (y = 7, 8; x = 0, 2, 4). The alloys were prepared by melt-spinning and then annealed at 973 K for 20 minutes. The magnetic ...
Effects of metal doping agent on the properties of Nb2−xMxO5 (M = Mn, Fe, and Ni) system
(International Journal Of Applied Ceramic TechnologyBogota , Colombia, 2018-05-21)
In order to improve the behavior Niobium pentoxide on oxidation-reductionreactions to degrade organic compounds in aqueous solutions, we developed the synthesis of Niobium pentoxide with the metal doping agents: manganese,iron, ...
