摘要
在Ｎａ２Ｏ－ＴｅＯ２系统中发现了一个未知的新晶相,探索了该晶相的确切成分和形成条件,并根据实验结果,对现有的相图作了相应的修改．该晶相的具体成分为Ｎａ２Ｏ·８ＴｅＯ２．此晶相在３３０℃下能稳定存在,当温度达到或高于３４０℃时则分解成Ｎａ３Ｏ·４ＴｅＯ２和ＴｅＯ２两个晶相．
A new crystalline phase with the composition of Na2O· 8TeO2(NT8) was found in the Na2O-TeO2 system and the formation and decomposition of this new crystalline phase was explored. The NT8 crystalline phase is stable at 330℃ or below, and decomposes to Na2O·4TeO2 and TeO2 at temperatures higher than 330-340℃. A modification to the phase diagram of the Na2O-TeO2 system was proposed according to this research.
