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.
