Ir Spectroscopy And X-Ray Phase Analysis Of Alkali-Free Fluorophosphate Glasses And Thier Crystalisation

On the basis of the IR-spectroscopic and x-ray phase analysis of alkali-free flurophosphate glasses and their crystallisation products it has been established that the main groups in glasses of the Ba(PO3)2 - MgF2 system are metaphosphate, pyrophosphate, monofluoro-phosphate, and magnesium fluorides structural units; b) in glasses of the system Ba(PO3)2 . 2AlF3 . 3CaF2 the main groups are metaphosphate, pyrophosphate, and fluoroaluminate structural groups. The crystallisation products of multicomponent glass containing phosphorous have been identified.
