Description

The system Nd(PO3)3 - KPO3 has been investigated by differential thermal analysis (during heating), thermogravimetric analysis, mass spectrometry, Raman spectroscopy and X-ray powder diffraction and its phase diagram was proposed. It was discovered that initial metaphosphates react at a 1:1 molar ratio forming intermediate compound KNd(PO3)4. It was found that it melts incongruently at 854 oC giving Nd(po)3)3 and a liquid rich in KPO3. Phosphate KNd(PO3)4 is stable down to room temperature and does not show any polymorphic transitions.
