We have studied the crystallization behavior of Na2O-NaPO3-MVIO3(MVI = Mo, W) high-temperature solutions containing 15 mol % Bi2O3 in the pseudoquaternary systems Na2O-Bi2O3-P2O5-MVIO3 and have established the conditions for the formation of Na3Bi(PO4)2, high-temperature BiPO4, NaBi(MoO4)2, Bi2WO6, and NaMoO2PO4. The compounds identified have been characterized by powder x-ray diffraction and IR spectroscopy.
