Disulfure de molybdène 1317-33-5

Overview of Molybdenum disulfide 1317-33-5

Molybdène (Mo) est un élément chimique de numéro atomique 42 and is represented by the symbol Mo on the periodic table. It is a transition metal located in group 6 and period 5. Molybdenum is known for its high melting point, excellent strength, and thermal stability, making it a crucial component in various industrial applications.

Feature of Molybdenum disulfide 1317-33-5

1. Point de fusion élevé: Molybdenum has one of the highest melting points among all pure elements, at 2,623°C (4,753°F). This property makes it ideal for high-temperature applications.

2. Strength and Toughness: Even at high temperatures, molybdenum maintains its strength and hardness, which is essential for use in extreme environments.

3. Corrosion Resistance: Molybdenum exhibits good corrosion resistance to many acids and alkalis, although it can be attacked by oxidizing acids like nitric acid.

4. Conductivité thermique: It is an excellent conductor of heat, making it suitable for applications where efficient heat transfer is required.

5. Alloying Agent: Molybdenum is widely used as an alloying agent, particularly with steel, to enhance hardness, toughness, and resistance to wear and corrosion. Stainless steels often contain molybdenum for these properties.

6. Electrical Applications: Due to its low resistivity and high-temperature stability, molybdenum is used in electrical contacts and heating elements.

7. Lubricity: Disulfure de molybdène (MoS₂) is a common dry lubricant, providing low friction surfaces in high-pressure, high-temperature conditions.
