Partial phase diagram of MoO3 rich section of the ternary Bi-Mo-O system

Partial phase diagrams of MoO3 rich section of Bi-Mo-O system have been established at 773, 873 and 1023 K based on phase equilibration studies. Electrical conductivity measurements along with equilibration experiments were used to determine the decomposition temperature of Bi2Mo2O9 and the polymorphic transformations of Bi2MoO6.
