磷锆硅酸钠(Na_3Zr_2Si_2PO_(12))是新近发现的一种Na~+离子导体,其300℃的电阻率可以和现在最好的Na~+离子导体Na-β″-Al_2O_3相比,且具有烧结温度比β-Al_2O_3低,耐湿性好等优点,是一种有希望的快离子导体(固体电解质).Goodenough和Hong用单晶试样测定过Na_3Zr_2Si_2PO_(12)的晶胞参数,并根据NaZr_2(PO_4)的晶体结构推测了Na_3Zr_2Si_2PO_(12)的晶体结构.至于Na_3Zr_2Si_2PO_(12)的X射线粉末衍射数据文献上未见报道,到1977年的国际X射线粉末衍射标准数据(JCPDS卡片)亦未收集过.本文
The Na ~ + ion conductor (Na_3Zr_2Si_2PO_ (12)) is a newly discovered Na ~ + ion conductor whose resistivity at 300 ℃ can be compared with that of Na ~ β "-Al_2O_3 which is the best Na ~ + ion conductor Is a promising fast ionic conductor (solid electrolyte) with sintering temperature lower than β-Al 2 O 3 and better moisture resistance.The unit cell parameters of Na_3Zr_2Si_2PO_ (12) were measured by single-crystal samples from Goodenough and Hong, The crystal structure of NaZr_2 (PO_4) has been deduced from the crystal structure of Na_3Zr_2Si_2PO_ (12). However, the XRD data of Na_3Zr_2Si_2PO_ (12) have not been reported in literatures. The international XRD data of JDPDS Uncollected. This article
