화학적 성질
Ammonium molybdate is a colorless, white or slightly greenish-yellow powder. It is used in chemical analysis for the determination of phosphorus. From a nitric acid solution it precipitates phosphorus in the form of ammonium phosphomolybdate having the formula (NH4)3PO4-12MoO3 after drying at 110 °C(230°F). Some of the phosphomolybdic acids are used as reagents for the alkaloids and in the analysis and separation of the alkali metals.

응용 분야
용도Ammonium molybdate has been used to prepare phosphomolybdates. (NH4)2MoO4 was used as an analytical reagent for quantitative analysis of phosphates, silicates, arsenates and lead in their aqueous solutions. At saturated concentration, (NH4)2MoO4 was used to perform cryo-negative staining and as a negative stain in biological electron microscopy. Ammonium molybdate was used in study of crystallisation of cell-free-expressed membrane proteins.
일반 설명Ammonium molybdate can be prepared by dissolving molybdenum trioxide in ammonia.
제조 방법
생산 방법Pure molybdic oxide (99.95% MoO3) is prepared by sublimation of technical oxide or by calcining ammonium molybdate. Metallic molybdenum powder is prepared commercially by hydrogen reduction of either pure molybdic oxide or ammonium molybdate in a two-step process.
