通过高温（１１７３—１４７３Ｋ）固相反应．制备了钠快离子导体ＮＡ３．３Ｚｒ１．６５－ＸＴｉＸＳｉ１．９ Ｐ１．１Ｏ１１．５系统中Ｘ＝０－１．６５的一系列合成物，研究了该系统的相变情况，探明了在ｘ＝０．５－０．９ 的组成范围内可制得ＮＡＳＩＣＯＮ单相．其中电导性最好的是Ｘ＝０．６的合成物．在６２３ｋ时它的电导 率为１８．９Ｓ·ｍ－１，在４７３—６７３Ｋ温区里其电导激活能为４１．７ＫＪ／ｍｏｌｅ．

Through high temperature (1173-1473K) solid phase reaction. A series of compositions of X = 0-1.65 in sodium fast ionic conductor NA3.3Zr1.65-XTiXSi1.9P1.1O11.5 were prepared. The phase transitions of the system were studied. It was found that when x = NASICON single phase can be made within the composition range of 0.5-0.9. Among them, the best conductivity is the composition of X = 0.6. Its conductivity was 18.9S · m-1 at 623k, and its conductance activation energy was 41.7KJ / mole at 473-673K.
