Procedure
171 grams of molybdenum trioxide (MoO3) were dissolved in a mixture of 433 ml of water and 215 ml of 57% ammonium hydroxide, added to a solution of 251.7 grams of bismuth trioxide (Bi2O3) in 833 ml of water and 367 ml of 70% nitric acid with stirring. The pH of the resulting mixtures were adjusted to between 1 and 6.5 using ammonium hydroxide and heated for approximately 2 hours at 100° C. The bismuth molybdate precipitate was filtered and washed with approximately 500 ml of water.
