Recent researches on structural control of the Na + superionic conducting glass-ceramics are also introduced. The optimum conditions for crystallization were discussed with reference to the conduction properties and the preparation of crack-free N5-type glass-ceramics. The effects of Si substitution with the various elements with tetrahedral oxygen coordination structure and Y substitution with the various R elements were also discussed on ionic conductivity of N5-type glass-ceramics, respectively.&nbsp;}, keywords = {Superionic conductor,Glass,Ceramics,crystallization,Na5YSi4O12,type,Microstructure}, url = {https://aml.iaamonline.org/article_13814.html}, eprint = {https://aml.iaamonline.org/article_13814_2641a1f858e45c074078e5d7b1290e69.pdf} }
