已经在实验上探索了用于快速Na+离子传输的骨架结构。骨架结构由刚性骨架原子阵列组成，所述刚性骨架原子阵列由碱金属离子提供的电子稳定，所述碱金属离子部分占据三维连接的间隙空间中的位点。Na+离子的快速传输在几种结构中得到了证实，Na 1+ x Zr 2 P 3− x Si x O 12系统在300° C下的Na+离子电阻率为300 Ω 5Ω-cm（x 12），与最好的β ″-氧化铝具有竞争力。活化能ε a = 0.29 eV，比β ″-Al_2O_3的活化能大0.1 eV。
Skeleton structures have been explored experimentally for fast Na+-ion transport. A skeleton structure consists of a rigid skeletal array of atoms stabilized by electrons donated by alkali ions partially occupying sites in a three dimensionally linked interstitial space. Fast Na+-ion transport was demonstrated in several structures, and the system Na 1+ x Zr 2 P 3− x Si x O 12 has a Na+-ion resistivity at 300° C of ϱ 300≲ 5Ω-cm for x≈ 2, which is competitive with the best β ″-alumina. An activation energy ε a≈ 0.29 eV is about 0.1 eV larger than that of β ″-alumina.
