Ammonium Molybdate Properties

Ammonium molybdate (Ammonium molybdate) is a chemical compound, usually in the form of tetrahydrate ((NH4)6Mo7O24 · 4H2O). It is a white or pale yellow crystalline powder, soluble in water, but insoluble in ethanol. The chemical properties of ammonium molybdate are relatively stable, but it will decompose to form molybdic acid and ammonia at high temperature. Its melting point is around 90°C and it has good thermal stability, which makes it widely used in high temperature environments. Ammonium molybdate is one of the important compounds of molybdenum, and its unique properties make it widely used in chemical and industrial fields.

Ammonium molybdate uses

Ammonium molybdate has a variety of uses in industry. It is an important intermediate for the production of other compounds and materials of molybdenum, such as molybdic acid, sodium molybdate, potassium molybdate and zinc molybdate. These compounds play a key role in the manufacture of catalysts, pigments and alloys. Ammonium molybdate is widely used in agriculture as a trace element fertilizer to supplement the lack of molybdenum in the soil, promote plant growth and increase crop yields. Ammonium molybdate is also used in the field of water treatment as a corrosion inhibitor and water quality stabilizer to prevent equipment corrosion and sediment formation. In analytical chemistry, ammonium molybdate is used as a reagent for the detection of phosphates, silicates and aluminium.

Ammonium molybdate upstream feedstock

The production of ammonium molybdate mainly depends on molybdenum ore (such as molybdenite) and ammonia. Molybdenum ore by pyrometallurgical or hydrometallurgical extraction of molybdenum oxide (MoO3), which is an important molybdenum source material. Then, molybdenum oxide is dissolved in aqueous ammonia and reacted to form an ammonium molybdate solution, which is evaporated and crystallized to obtain an ammonium molybdate product. Ammonia, as a source of nitrogen, reacts with molybdenum oxides to produce ammonium molybdate, so the supply and price fluctuations of ammonia also affect the production cost of ammonium molybdate.

Ammonium molybdate downstream products

The downstream products of ammonium molybdate are widely used in various fields. In the field of catalysts, ammonium molybdate can be used to produce hydrocracking catalysts and selective oxidation catalysts, which are widely used in petrochemical and environmental protection industries. In the field of metal alloys, ammonium molybdate is an important raw material of molybdenum alloys. These alloys have excellent characteristics such as high strength, high melting point and corrosion resistance, and are widely used in aerospace, electronics and military industries. Ammonium molybdate is also used in the production of molybdate pigments, which have good light, heat and chemical resistance and are used in the coatings and plastics industries. The application of ammonium molybdate in agriculture can not be ignored, it is an important part of plant nutrition, promote plant growth and development, improve the yield and quality of crops.

Ammonium Molybdate Storage Method

Ammonium molybdate has a certain moisture absorption, so it is necessary to pay attention to moisture during storage. Generally, ammonium molybdate should be stored in a dry, ventilated environment to avoid contact with water and moisture. Ammonium molybdate should be stored in a cool place, avoid direct sunlight and high temperature environment to prevent decomposition. Ammonium molybdate packaging materials are usually sealed plastic bags or moisture-proof paper bags, plus protective barrels or boxes to prevent moisture and contamination. During storage and transportation, contact with acidic substances should be avoided, because the acidic environment may cause decomposition and performance degradation of ammonium molybdate.

Market Analysis and Prospects

Ammonium molybdate is an important chemical raw material and intermediate, and its market demand is driven by many industries. With the development of global agricultural modernization, the demand of ammonium molybdate in the agricultural field has been increasing steadily. With the increasingly stringent environmental regulations and the advancement of industrialization, ammonium molybdate has a broad application prospect in the field of water treatment and catalyst. The continuous development of high-performance alloys and new materials also provides a new growth point for the application of ammonium molybdate in metal processing and new materials industry. On the whole, the ammonium molybdate market has a good prospect and is expected to maintain stable growth in the next few years.

Environmental and Safety Considerations

Attention should be paid to environmental protection and safety issues in the production and use of ammonium molybdate. The mining and smelting process of molybdenum ore will produce waste water and waste gas, and effective environmental protection measures should be taken to reduce environmental pollution. During the production and storage of ammonium molybdate, it is necessary to strictly control the emission of ammonia gas to avoid pollution to the atmospheric environment. Although ammonium molybdate itself is less toxic, it will release ammonia during high temperature decomposition. Therefore, appropriate protective measures should be taken during use to prevent inhalation of high concentrations of ammonia.

Conclusion

As an important chemical product, ammonium molybdate has a wide range of applications and good market prospects. Its production relies on molybdenum ore and ammonia, involving complex chemical reactions and high environmental standards. During use and storage, attention should be paid to moisture-proof, pollution-proof and safety protection. With the advancement of global industrialization and the improvement of environmental protection requirements, the application of ammonium molybdate will be more extensive, and the market demand will also grow steadily. In the future, the application prospect of ammonium molybdate in agriculture, industry and environmental protection will be more broad, which is worthy of continuous attention and research.
