Quick Summary

Ammonium molybdate is a white crystalline salt used in analytical chemistry. It serves as a precipitant for phosphoric acid, forming a yellow precipitate known as ammonium phosphomolybdate. Molybdate compounds, in general, contain the group MoO₄ or Mo₂O₇ and are salts of molybdic acid. These compounds are derived from molybdenum, a refractory metal known for its ability to strengthen steel at high temperatures. Molybdenum itself is not found freely in nature but is extracted from ores, primarily molybdenite. Chemically pure molybdic oxide is a precursor for various molybdenum compounds, including ammonium molybdate, which is used in the preparation of molybdenum chemicals and catalysts.1234

…suitable for the manufacture of ammonium molybdate (ADM) and sodium molybdate, which are starting materials for all sorts of molybdenum chemicals. These compounds are obtained by reacting chemically pure MoO₃ with aqueous ammonia or sodium hydroxide. Ammonium molybdate, in the form of white crystals, assays 81 to 83 percent MoO₃,…
