Product Description
Ammonium Molybdates Tetrahydrate (CAS 12054-85-2)
High-Purity Molybdenum Source
Ammonium molybdates tetrahydrate, with the chemical formula (NH₄)₆Mo₇O₂₄·4H₂O and CAS registry number 12054-85-2, is a vital inorganic salt and primary source of molybdenum. It appears as colorless or slightly yellow-green crystalline powder, highly soluble in water. This compound is an essential precursor in the chemical industry, serving as a catalyst, corrosion inhibitor, fertilizer additive, and key raw material for producing molybdenum metal and other molybdenum compounds. Its consistent quality and reactivity make it indispensable for industrial and research applications.

- Flame Retardant & Smoke Suppressant: An additive in plastics, paints, and textiles.
Application Areas
- Agriculture: As a micronutrient fertilizer to correct molybdenum deficiency in crops like legumes, crucifers, and citrus.
- Chemical Manufacturing: A key raw material for producing molybdenum trioxide (MoO₃), molybdenum metal, and other molybdenum salts.
- Petrochemical Industry: A crucial catalyst component for desulfurization and hydrogenation processes.
- Water Treatment: Used as a non-chromate, environmentally friendlier corrosion inhibitor in cooling systems.
- Pigments & Ceramics: For manufacturing high-stability, colored pigments (e.g., molybdates orange/red) and ceramic glazes.
- Electroplating: For depositing molybdenum-containing alloy coatings.
- Laboratory & Research: As a standard reagent in analytical chemistry and material science research.
Manufacturing Process
Our high-purity Ammonium Molybdates Tetrahydrate is manufactured through a controlled process:
- Raw Material Leaching: High-grade molybdenum concentrate (MoS₂) is roasted to produce technical molybdenum trioxide (MoO₃).
- Purification: The crude MoO₃ is dissolved in an ammonium hydroxide solution, forming ammonium molybdates.
- Crystallization: The solution undergoes precise evaporation and cooling under controlled conditions to crystallize the tetrahydrate form.
- Filtration & Washing: The crystals are separated, washed with high-purity water to remove impurities like chlorides and sulfates.
- Drying & Sieving: The product is gently dried at a controlled temperature to preserve the hydrate structure, then sieved to ensure uniform particle size.
- Quality Control: Every batch undergoes rigorous analysis (ICP, AAS, titration) to confirm compliance with specifications before packaging.

FAQ (Frequently Asked Questions)
Q1: What is the difference between ammonium molybdates and ammonium heptamolybdates tetrahydrate?
A: They refer to the same common compound. The systematic name is ammonium heptamolybdates tetrahydrate, but it is widely known and sold as ammonium molybdates tetrahydrate (CAS 12054-85-2).
Q2: How should this product be stored?
A: Store in a cool, dry, and well-ventilated place. Keep the container tightly sealed to prevent absorption of moisture and CO₂ from the air, which can affect solubility and purity.
Q3: Is it hazardous?
A: It is generally considered a low-hazard substance but can cause eye and skin irritation. Always refer to the Safety Data Sheet (SDS) and use appropriate personal protective equipment (PPE) like gloves and goggles.
Q4: Can you supply this product in different grades?
A: Yes. We supply various grades, including Technical Grade, Reagent Grade (ACS), and Agriculture Grade. Please contact us to discuss your specific requirements.
Q5: What is the typical packaging?
A: We offer flexible packaging: 25 kg bags (kraft paper with PE liner), 50 kg drums (HDPE), or customized packaging to meet your logistical needs.
Q6: What is the lead time for orders?
A: For standard grades, we often have ready stock. Lead times vary based on order quantity and customization. Contact our sales team for an accurate timeline.
