低温燃烧法制备掺杂NiO的Beta-Al2 O3固体电解质
Preparation of NiO Doped Beta-Al2 O3 Solid Electrolyte via a Low Temperature Combustion Method
摘要
Abstract
NiO doped and Li2 O stabilized Beta-Al2 O3 solid electrolyte was synthesized via a citrate sol-gel low temperature combustion method. Effects of the NiO content on the mechanical and electrical performances were 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 were also measured. When the content( mass fraction) of NiO in Beta-Al2 O3 solid electrolyte is 0. 10%, the content of β〞-Al2 O3 phase is 88. 33%, the microstructure is uniform and compact, the relative density is 99. 75%, the bending strength is up to 248 MPa and the ionic conductivity can reach 0. 108 S/cm at 350 ℃.关键词
