Molybdenum Powder Properties

Description of Molybdenum Powder :

Molybdenum powder is a gray metal molybdenum powder; its molecular formula is Mo, its molecular weight is 95.95, and its specific gravity is 10.22. The appearance of molybdenum powder is loose, dry, and easy to flow fine particles with good adhesion and dispersion. Its melting point is high, the boiling point is high, the high temperature is not volatile, has good thermal and chemical stability. Molybdenum powder is widely used in cemented carbide, diamond tools, high-temperature corrosion-resistant alloys, and other fields. In the cemented carbide industry, molybdenum powder is one of the important raw materials, with tungsten carbide powder, made of cemented carbide products, with high hardness, high strength, good wear resistance, thermal stability, and other advantages. In the diamond tool industry, molybdenum powder can be used as a binder and matrix material to improve diamond tools' cutting performance and life. Molybdenum powder is one of the important alloying elements in high-temperature corrosion-resistant alloys, which improves the strength at high temperatures that can improve the creep resistance, strength, and resistance to corrosion of alloys. This can increase the strength, creep resistance, and corrosion resistance. It should be noted that the explosive sensitivity of molybdenum powder is high, and the fire source should be strictly controlled during production, use, and storage to prevent explosion accidents. In addition, molybdenum powder is easily oxidized, and measures should be taken to prevent its contact with oxygen in the air.

Production Method of Molybdenum Powder :

Molybdenum powder production methods are mainly the hydrogen reduction method of molybdenum oxide and the carbon reduction method of molybdenum ore. 

1. Hydrogen reduction method of molybdenum oxide 

The hydrogen reduction method of molybdenum oxide is one of the main methods of producing molybdenum powder, including a two-step reduction process, which first reacts MoO3 with hydrogen at a high temperature to generate MoO2 and then further reduces MoO2 to Mo powder. 

The first reduction reaction is MoO3 + H2 → MoO2 + H2O, which needs to be carried out at high temperatures in the range of 500-600°C. MoO3 loses oxygen atoms during the reaction to form MoO2, generating water. The reaction requires sufficient hydrogen and high-temperature conditions to ensure that the reaction can proceed smoothly. 

The second reduction reaction is MoO2 + H2 → Mo + H2O, which needs to be carried out at higher temperatures, ranging from 900 to 1100°C. During the reaction, MoO2 loses oxygen atoms to form Mo powder, forming water. The reaction also requires sufficient hydrogen and high-temperature conditions to ensure that the reaction can proceed smoothly. 

Two, molybdenum carbon reduction method 

The carbon reduction method of molybdenum ore is another method of producing molybdenum powder, which involves reacting molybdenum ore with carbon at high temperatures to produce MoO2 and gases such as CO or CO2, and then further hydrogen reduction of MoO2 to Mo powder. 

Specific reactions include: MoS2 + 3CO → Mo + 2CO2 + S, MoO2 + 2C → Mo + 2CO, and MoO2 + H2 → Mo + H2O. During the reaction, sulfur and oxygen are removed from the molybdenum ore, producing gases such as MoO2 and CO or CO2. The resulting MoO2 is then further hydrogen-reduced to Mo powder. In addition, it should be noted that in the production process of molybdenum powder, Many pollutants like wastewater, waste gas, and solid waste are generated in the coming years, which not only pollute the environment but also pose a potential threat to production safety. Therefore, in the production process, it is essential to implement efficient environmental protection measures and production security measures to ensure production processes meet the environmental protection and safety rules and safeguard the health and safety of the workers.


Molybdenum powder Uses:

Metallurgy: Adding Mo powders to stainless steel and other alloys can improve composite alloys' corrosion resistance hardening properties and bring many other benefits to the final result.

Electronic products: the unique characteristics of molybdenum make molybdenum nanometer powder the key material for the manufacture of various high-pressure vacuum tubes, heat tubes, X-ray tubes, and so on.

Wood processing: Molybdenum powder is widely used in wood processing as a supplement to catalysts.

Coatings: Molybdenum is known as the preferred coating for high-friction, heavy-duty environments due to its extreme lubrication. Molybdenum provides a simple and effective method for applying this coating with extreme accuracy.

High-temperature lubrication: Because the lubricant needs to withstand high temperatures, molybdenum-based synthetic grease is very good. Molybdenum nanoparticles play a crucial role in the manufacture of these high-temperature lubricants.


Storage Condition of Molybdenum Powder 3N Mo Powder CAS 7439-98-7 :

The damp reunion will affect molybdenum powder dispersion performance and use effects. Therefore, Mo powder should be sealed in vacuum packing and stored in a cool and dry room, and the molybdenum powder can not be exposed to air. In addition, the product should be avoided under stress.
