Crystalline Phase (Na₂O · 8TeO₂) Formed During Heat-Treatment of Na₂O-TeO₂ System
A new crystallin 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°C or below, and decomposes to Na2O·4TeO2 and TeO2 at temperatures higher than 330-340°C. A modification to the phase diagram of the Na2O-TeO2 system was proposed according to this research.
