What Are the Uses of Tantalum and Its Alloys? Tantalum is the third most refractory metal, with a melting point of 2980℃, only after tungsten and rhenium. Besides, tantalum also has other excellent properties like low vapor pressure, good cold workability, high chemical stability, strong resistance to liquid metal corrosion, and a large dielectric constant […]

Rhenium is added to high-temperature superalloys that are used to make jet engine parts, using 70% of the worldwide rhenium production. Another major application is in platinum–rhenium catalysts, which are primarily used in making lead-free, high-octane gasoline. Nickel-based superalloys have improved creep resistance with the addition of rhenium. Alloys normally contain 3% or 6% rhenium. […]
What Can Rhenium Be Used For? Rhenium is classified as a scarce refractory metal. It has the second-highest melting point of any of the metals and has a relatively high density. Rhenium is produced as a powder from molybdenite, which also contains rhenium sulfide. The rhenium powder is consolidated by pressing and resistance sintering in […]

The List Of Abundant Refractory Metals Tungsten, tantalum, molybdenum, columbium, vanadium, and chromium may be classed as relatively abundant refractory metals; that is, free world reserves of contained metal are over 100,000 tons for each metal. The first four show promise in a considerably higher temperature range than the last two, and sometimes the term […]

How Do We Use Molybdenum? Molybdenum, whose chemical symbol is Mo, was first recognized as an element in 1778. Until that time, the mineral molybdenite—the most important source of molybdenum—was believed to be a lead mineral because of its metallic gray color, greasy feel, and softness. In the late 19th century, French metallurgists discovered that […]

The Role of Niobium in Superalloys Refractory elements are important alloying additions in both nickel-base and iron-nickel-base superalloys. They are responsible for the increased high-temperature mechanical properties present in current superalloy systems. In this article, we’ll take a look at the role of niobium in superalloys. It has long been established that nickel-base and iron-nickel-base […]
