molybdenum trioxide CAS. 1313-27-5 MoO3

Overview of molybdenum trioxide CAS. 1313-27-5 MoO3

molybdén (Mo) is a chemical element with the atomic number 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 trioxide CAS. 1313-27-5 MoO3

1. High Melting Point: 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. Tepelná vodivosť: 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: Molybdenum disulfide (MoS₂) is a common dry lubricant, providing low friction surfaces in high-pressure, high-temperature conditions.

Parameters of molybdenum trioxide CAS. 1313-27-5 MoO3

Molybdenum trioxide (MoO3) is a chemical compound with the molecular formula MoO3 and the following physical properties:

CAS Number: 1313-27-5

MoO3 stands for magnesium oxide trioxide, which is the compound formed when magnesium reacts with oxygen in the presence of water.

Specifically, when magnesium reacts with oxygen in water at standard conditions (298 K and atmospheric pressure), it produces magnesium oxide (MgO) along with water (H2O). The reaction can be represented as:
Mg + O2 → MgO
3MgO → 3MgO

The specific heat capacity of MoO3 is not well-defined, but it is estimated to be around 60 J/g·K or 3400 J/mol·K at standard temperature and pressure. The density of MoO3 is also not very well-known, but it is approximately equal to that of water at room temperature and pressure.

Molybdenum trioxide has some potential applications in industries such as electronics, materials science, and aerospace. It is used as a refractory material in ceramics, glassware, and other high-temperature applications, and it is also used as a catalyst in various chemical reactions.
