Refractory metals broadly refer to the metals with a melting point of above 2000°C, mainly tungsten (W), molybdenum (Mo), tantalum (Ta), niobium (Nb), and rhenium (Re), among others. Refractory metals have excellent properties like high melting points, high strength, low thermal expansion coefficients, low resistivity, and good thermal stability. Therefore, they play a vital role in numerous applications, for example, in aerospace, electronics, nuclear power, semiconductor lighting, medicine, and machinery under high temperature and pressure.

FAQs
1. Which Refractory Metal Powder Has the Highest Melting Point?
Powder of tungsten (W) has the highest melting point of 3422°C, which is the highest among all metals.
Properties And Applications Comparison of Refractory Metals: Molybdenum vs. Tungsten vs. Niobium vs. Tantalum
2. Tungsten (W) vs. Tantalum (Ta) differences
Tungsten has a higher melting point (3422°C vs. 3017°C) and greater density (19.3 vs. 16.6 g/cm³) than tantalum. Tantalum is extremely corrosion-resistant, resisting acids, alkalis, and even aqua regia, and is hence well-suited for chemical and medical applications. Tungsten, while extremely heat-resistant, oxidizes at elevated temperatures and finds application predominantly in ultra-high-temperature applications like rocket nozzles and armor-piercing projectiles.
3. Differences Between Tungsten (W) and Molybdenum (Mo)
Tungsten has a far greater melting point (3422°C versus 2623°C) and is denser (19.3 versus 10.2 g/cm³) than molybdenum. Molybdenum is easier to process and less costly and finds extensive use in high-temperature furnaces and electronic devices. Tungsten, due to its excellent resistance to heat and hardness, is utilized in applications of extremely high temperatures such as rocket motors and nuclear applications.
