Glass-forming region in the system Li3PO4–Pb3(PO4)2–BiPO4 (Li2O–PbO–Bi2O3–P2O5) and its ionic conductivity

The glass-forming region in the system Li3PO4–Pb3(PO4)2–BiPO4 (Li2O–PbO–Bi2O3–P2O5) was determined and a study of ionic conductivity of glasses belonging to this system was carried out. The ionic conductivity, σ, increases substantially with increasing concentration of lithium oxide and diminishes with increasing concentration of either PbO or Bi2O3.
