通过高温固相反应合成了钠快离子导体Ｎａ３－ｘＺｒ２－ｘＶｘＳｉ２ＰＯ１２系统的一系列合成物、其合成反应均可在低于１３７３Ｋ的温度下完成，且该系统的合成温度随ｘ增大而降低．Ｘ－射线衍射数据表明，当ｘ＜０．５时，其合成物为ＮＡＳＩＣＯＮ单纯相，其空间群为Ｃ２／ｃ，当ｘ＞０．５时，合成物开始玻璃化。系统合成物的有关晶胞参数随ｘ的增大而相应缩小，电性能测定结果表明，最好电导性的起始组成为ｘ－０．１．其导电率在室温时为５．４５×１０－４Ｓ·ｃｍ－１，在７２３Ｋ时为１．０４×１０－１ｓ·ｃｍ－１，其电导激活能为 ２３．４６ｋＪ／ｍｏｌ。
A series of sodium fast ionic conductor Na3-xZr2-xVxSi2PO12 systems were synthesized by solid-state reaction at high temperature. The synthesis reaction can be completed at temperatures below 1373K. X-ray diffraction data showed that when x <0.5, its composition was NASICON pure phase with space group C2 / c. When x> 0.5, the composite began to vitrify. The relevant unit cell parameters of the system composition decrease correspondingly with the increase of x, and the result of electrical property measurement shows that the best initial composition of conductivity is x-0.1. The conductivity was 5.45 × 10-4S · cm-1 at room temperature and 1.04 × 10-1s · cm-1 at 723K, and the conductance activation energy was 23.46kJ / mol.
