Abstract

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.
