摘要: 以薄水铝石、氧化镁、碳酸钠为起始原料, 采用传统的固相反应法并添加0.5%--2%的TiO2促进烧结, 制备出高致密度的Na--β''--Al2O3电解质, 并对不同TiO2添加量样品的相组成、微结构、力学性能以及电性能进行表征。结果表明, 添加TiO2所得Na--β''--Al2O3材料的相纯度高于96%; 未添加TiO2的烧结试样结构疏松, 存在大面积孔缺陷, 而添加TiO2的试样显微结构均一, 颗粒排布紧密, 晶粒生长完善, 致密度明显提高。添加TiO2可以显著提高材料的弯曲强度; 添加TiO2使致密烧结体的钠离子电导率有大幅度提高, 其原因是高致密度减小了材料的晶界电阻。

Abstract：The Na–β''–Al2O3 electrolyte materials with the relative density of 98% were synthesized by a solid state reaction route employing boehmiteNa2CO3MgO as starting materials and TiO2 as additive and characterized by X-ray diffraction, SEM, bending strength testing and AC 4-probe method. The results show that TiO2 can promote the sintering performance of Na–β''–Al2O3 electrolyte effectively and the purities of β phases were all above 96% when the content of TiO2 ranging from 0.5%–2%. The obtained samples with TiO2 dopants comprised of compact and plump grains exhibiting high density with uniform microstructure. The bending strength of the specimen was enhanced obviously with the increase of the TiO2 additives. The ionic conductivity increased compared with the plain sample due to the decreased boundary resistance of the material.

Key words： inorganic non–metallic materials solid–state reaction TiO2 Na–β''–Al2O3 solid electrolyte
