description Compositions for forming sodium ion conductive electrolyte structures are provided, the compositions comprising particles of a sodium ion conductive ceramic in combination with particles of at least one transition metal oxide (e.g., copper, titanium and niobium oxides, or iron oxides, or precursors of these oxides), such that the metal oxide comprises no more than 5% by weight of the weight of the particles. Sodium ion conductive ceramics may have the type referred to as Nascon or [beta] ''-alumina. The metal oxide may comprise no more than 2% by weight of the particles. The metal oxide is used as a sintering aid, so that densification can be realized at a reduced sintering temperature, and meanwhile, no obvious adverse effect is generated on the electrical property of the sintered ceramic. The invention also includes an electrode structure made by sintering the composition. 提供用于形成钠离子导电电解质结构的组合物，所述组合物包含与至少一种过渡金属氧化物(例如铜、钛和铌氧化物，或铁氧化物，或这些氧化物的前体)的颗粒组合的钠离子导电陶瓷的颗粒，因此金属氧化物占不超过颗粒重量的5％重量。钠离子导电陶瓷可以具有称为Nasicon或β"-氧化铝的类型
