Seven glass compositions were synthesised in the systems Ba(PO3)2-MgF2 and Ba(PO3)2-2AlF3.3CaF2. Predominant groups in the 1st system are metaphosphatic, pyrophosphatic, monofluorophosphatic, and MgF2 structural units. In the second system metaphosphate, pyrophosphate and fluoroaluminate groups predominate. Crystallisation products identified were a-Ba2P2O7, BaMgP2O7, a-Ca2P2O7, a-CaF2AlF3, etc.
