Research on influence of sintering temperature on performance of Na_2O·5Al_2O_3 solid electrolytes

Na2O·5 Al2O3 solid electrolytes were synthesized by solid state reaction. The formation of /b phase,density and ionic conductivity of Na2O·5 Al2O3 was studied with sintering temperature by XRD and EIS. The results show that the b phase content increases with the increasing of sintering temperature, and the density and ionic conductivity of the electrolyte sinters are optimized.
