Ammonium Molybdate: Forms, Properties, Uses, and Market Dynamics

Forms of Ammonium Molybdate

Ammonium molybdate exists in three different forms:

• Ammonium Dimolybdate ((NH₄)₂Mo₂O₇)

• Ammonium Tetramolybdate ((NH₄)₂Mo₄O₁₃·2H₂O)

• Ammonium Heptamolybdate ((NH₄)₆Mo₇O₂₄·4H₂O)

Ammonium heptamolybdate tetrahydrate is identical to ammonium heptamolybdate, as it contains four water molecules (4H₂O). Our company supplies ammonium molybdate in the most suitable form for your specific applications.

Chemical Information

• Molecular Weight: 196 g/mol

• Chemical Name: Ammonium Molybdate Tetrahydrate

• CAS Number: 12054-85-2

Chemical Formula and Structure

Ammonium molybdate is represented by the chemical formula (NH₄)₂MoO₄, consisting of ammonium ions (NH₄⁺) and molybdate ions (MoO₄²⁻). The compound is formed through the combination of these ions, where the positively charged ammonium ion consists of nitrogen and hydrogen atoms, and the negatively charged molybdate ion consists of molybdenum and oxygen atoms.

Applications of Ammonium Molybdate

1. Agriculture: Used as a micronutrient in fertilizers to provide essential molybdenum for plant growth. It plays a vital role in nitrogen fixation, photosynthesis, and seed formation, particularly benefiting crops such as legumes, wheat, maize, and potatoes.

2. Metallurgy: Applied in steel manufacturing to enhance hardness and strength and acts as a catalyst in aluminum production for improved purity.

3. Chemical Industry: Utilized as a catalyst in organic synthesis, particularly in molecular hydrogen transfer reactions.

4. Ceramics and Paints: Used in pigment production for yellow and red color formulations.

5. Photography: Employed in the preparation of photographic chemicals.

6. Petrochemical Industry: Functions as a catalyst in various refining and chemical processes.

Preparation of Ammonium Molybdate Solution

Ammonium molybdate solutions are widely used in analytical chemistry and industrial applications. The preparation process includes:

• Measuring the required amount of ammonium molybdate salt.

• Dissolving the salt in distilled water in an appropriate container.

• Stirring thoroughly until a homogeneous solution is obtained.

• Storing the solution under suitable conditions for later use.

Factors Influencing Ammonium Molybdate Prices

The price of ammonium molybdate fluctuates based on several factors:

1. Molybdenum Market Trends: Availability and global demand for molybdenum influence pricing.

2. Agricultural Demand: Since it is widely used in fertilizers, fluctuations in agricultural production impact its cost.

3. Production and Supply Chain Costs: Factors such as raw material availability, manufacturing processes, and distribution expenses affect pricing.

4. Economic Conditions: Exchange rates, energy costs, and market trends play a role in determining price variations.

Production of Ammonium Molybdate

The production process involves several key stages:

1. Extraction of Molybdenite: Molybdenite (MoS₂), the primary molybdenum ore, is extracted.

2. Oxidation: The extracted molybdenite is oxidized to convert it into molybdenum oxides.

3. Reaction with Ammonium Ions: Oxidized molybdenum reacts with ammonium ions (NH₄⁺), forming ammonium molybdate.

4. Crystallization: The solution undergoes controlled cooling, allowing crystals to form.

5. Drying and Purification: The crystallized ammonium molybdate is purified and dried for commercial use.
