What is the melting point of molybdenum? Learn about the high temperature applications and properties of molybdenum

Molybdenum is a refractory metal known for its extremely high melting point, one of its most notable properties. The melting point of molybdenum is consistently reported as 2610°C (or 2895 K) in multiple references, making it one of the highest melting metals. This property, along with its high creep resistance, low thermal expansion, and excellent corrosion resistance, makes it a material of choice for high-temperature applications such as furnaces, aerospace components, and industrial machinery. Molybdenum is widely used in industries such as glass manufacturing, where its ability to withstand extreme temperatures without noticeable deformation or degradation further enhances its usefulness in a variety of high-performance applications.

Molybdenum Melting Point:

Molybdenum has a melting point of 2610°c (2895 K) as confirmed by multiple references. This places it among the metals with the highest melting points, making it suitable for extreme temperature environments.
This property is critical for applications such as high-temperature furnaces, where the material must maintain structural integrity at high temperatures.
Comparison with other metals:

Molybdenum has a lower melting point than tungsten (3422°C), but higher than many other metals, such as titanium (1668°C) and iron (1538°C). Therefore, molybdenum is a practical choice for applications that require high-temperature resistance but better machinability than tungsten.
High-temperature applications:

Molybdenum is widely used in the glass industry, which is important in these environments due to its ability to withstand high temperatures without staining or reacting with the molten glass. Its dimensional stability and durability are critical in these environments.
It is also used in the aerospace and defense industry for parts exposed to extreme heat, such as rocket nozzles and turbine blades.
Physical and chemical properties:

Density: 10.2 g/cm3 at 0°C, which contributes to its strength and durability.
Thermal conductivity: 142 W/m-K at 20°C, which allows for efficient heat dissipation in high-temperature applications.
Corrosion Resistance: In the absence of oxidizing agents, molybdenum has a strong resistance to corrosion by acids, molten metals, and glass. Therefore, it is well suited for use in chemically aggressive environments.
Advantages over Other Refractory Metals:

Molybdenum is more ductile and easier to form than tungsten, making it more versatile in manufacturing processes.
Molybdenum has a lower melting point than tungsten, but this does not seriously limit its use as it still performs well in most high-temperature applications.
Alloys and Enhancements:

The properties of pure molybdenum can be further enhanced by alloying, which improves its performance in specific environments. For example, TLWM (Tungsten-Lanthanum-Molybdenum) alloys have excellent performance under high temperature and high stress conditions.
Other Properties:

Electrical Conductivity: With an IACS of 34% at 0°C, it can be used in electrical applications that require thermal and electrical conductivity.
Reflectivity: 46% at 500nm and 93% at 10,000nm, respectively, which facilitates its use in optical and reflective applications.
Practical considerations for buyers:

When selecting molybdenum for high temperature applications, buyers should consider its melting point, thermal conductivity and corrosion resistance to ensure that the operating requirements are met.

Its ductility and easy formability make it a cost-effective choice compared to other difficult-to-process metals such as tungsten.

In summary, molybdenum's high melting point of 2610°C, combined with its excellent thermal, mechanical and chemical properties, make it a versatile and reliable material for high temperature and corrosive environments. Molybdenum's advantages over other refractory metals such as tungsten further enhance its appeal in industrial and technological applications.
