“…Ma [17] found that NiO doping could improve sintering properties and electrical conductivity of 4YSZ. Xiao et al [18], who doped with different concentrations of Ni in Bi4NdTi3FeO15 ceramics, found that a small amount of Ni doping didn′t change the structure of ceramic but improved the properties. Das et al [19] pointed out that the magnetic of BTO ceramics was also enhanced with the increasing of the NiO concentration.…”

The beta-Al2O3 solid electrolyte with NiO doped and Li2O stabilized is synthesized via the solid state reaction method, which is starting with α-Al2O3, Li2CO3, Na2C2O4 and Ni(NO3)2•6H2O as the raw materials. Effects of the NiO content on the mechanical and electrical performances are studied by means of thermogravimetry/differential scanning calorimetry (TG/DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Meanwhile, the relative density, the bending strength and the electrical properties of the prepared samples are also measured in this paper. The beta-Al2O3 solid electrolyte with the appropriate amount of NiO has a higher β"-Al2O3 phase content and uniform microstructure with dense and plump grains. However, the excess NiO doping can lead the grain to molten state and make the pores become larger. It deteriorates the ionic conductivity. When the NiO content of the beta-Al2O3 solid electrolyte is 0.25wt%, the β"-Al2O3 phase

“…The sample exhibits a typical ferromagnetic M-H loop, with remnant magnetization (2M r ) of $232 m emu/g and coercive field (2H c ) of $769 Oe respectively. The measured 2M r is much larger than that of undoped BTF (122 l emu/g) [23], which might attributed to the occurrence of strong direct Fe-O-Co interaction when the doping concentration of magnetic ion (here refers to Co) is 30% [24] and the release of large latent magnetization locked in the antiferromagnetic state because of the radii differences of Bi and Nd, Fe and Co ions. According to the results of Fig.…”

“…The partial substitution of Ni for Mn in MnZn ferrites can improve their ferromagnetic behavior due to the absence of antiferromagnetic hematice and the less inter-and intrapores in the doped materials [1]. The influence of Ni doping on multiferroic behaviors in Bi 4 NdTi 3 FeO 15 ceramics was found that 10% Ni can increase the space charge created by oxygen vacancies, thus resulting in an improved dielectric loss [3]. Also it is found that Ni doping could improve the magnetic properties of α-MnO 2 to a certain extent [4,5].…”
