Phase equilibria in the Zn2P2O7-M2ZnP2O7 and M′2ZnP2O7-M″2ZnP2O7 (M, M′, M″ = Li, Na, K) glass-forming systems

Data are presented on the phase relations in the Zn2P2O7-M2ZnP2O7 and M′2ZnP2O7-M″2ZnP2O7 (M, M′, M″ = Li, Na, K) systems. The stable and metastable phase equilibria in these systems have been investigated, new compounds have been identified, and wide solid-solution ranges have been found. Some of the physicochemical properties of the synthesized phases are described.
