What Can Rhenium Be Used For?

0 Comment

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 […]

How Chromium Works?

0 Comment

How Chromium Works? In this article, we will take a look at how chromium works. The melting point of chromium is the lowest of the abundant refractory metals, but it is more than 700 degrees above that of iron. The density of chromium is slightly less than that of iron. At elevated temperatures, it acquires […]

Will Molybdenum Combine with Other Elements?

0 Comment

Will Molybdenum Combine with Other Elements? Molybdenum. As shown in Table 2, the melting temperature of molybdenum is 695 degrees below that of tantalum. Because of its high melting point and relative abundance in the United States, it was the first of the refractory metals considered in this country for high-temperature structural applications. The primary […]

How Do We Use Molybdenum?

0 Comment

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

0 Comment

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 […]

Which Elements Have the Highest Melting Point?

0 Comment

Which Elements Have the Highest Melting Point? As we all know, the melting point is the temperature at which substance converts from solid-state to liquid state. Some of the metals show very high melting points at least 2,000 degrees Celsius, and they also have very high physical strength. These metals are named as refractory metals. […]

How Titanium Is Used Today?

0 Comment

How Titanium Is Used Today? In today’s article, we’ll take a look at how titanium is used today. Titanium is a hard, shiny and strong metal. It is as strong as steel but much less dense. It is therefore important as an alloying agent with many metals including molybdenum, aluminium, and iron. Titanium metal connects well with […]
