Beryllium Metal Properties & Reasons Why It Can Be Applied For Missile

0 Comment

Why Can Beryllium Metal Be Applied For Missile? Beryllium metal is a material with a relatively special performance, some properties of which are irreplaceable by any other metal materials, especially nuclear properties and physical properties. Beryllium is mainly concentrated in the nuclear industry, the application scope of the weapon system, aerospace industry, X-ray instruments, electronic information […]

What Happens if Rhenium Is Alloyed to Niobium, Tungsten, and Tantalum?

0 Comment

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. […]

Hafnium Oxide And Its Structure & Applications

0 Comments

Hafnium Oxide and Its Structure And Applications  Hafnium oxide is the inorganic compound of the formula HfO2. Also known as hafnia, this colorless solid is one of the most common and stable compounds of hafnium. It is an electrical isolator with a bandgap of 5.3 ~ 5.7 eV. Hafnium dioxide is an intermediate in some […]

What Hafnium Is Used For?

0 Comment

What Hafnium Is Used For? Hafnium occurs in zirconium ores. Because this metal must be removed from “reactor-grade” zirconium, the production of hafnium is largely dependent on zirconium production, as discussed later. Its melting point is 4032℉. However, it has not been available in sufficiently large quantities to have any extensive elevated-temperature applications other than […]

Why Platinum Is The Most Expensive Metal?

0 Comments

Why Platinum Is The Most Expensive Metal? The platinum-group metals can be described as refractory metals because of their high melting points. This group comprises platinum, osmium, iridium, ruthenium, rhodium, and palladium, i.e., metals that have properties similar to those of platinum. The metals in this group are quite scarce and expensive, such as platinum, […]

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 Does Chromium Work?

0 Comment

How Does Chromium Work? 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 […]

Why Is Vanadium A Transition Metal?

0 Comment

Why Is Vanadium A Transition Metal? The melting point of vanadium is about 1000 degrees lower than that of columbium, so there is much less interest in vanadium for high-temperature applications than in abundant refractory metals. Pure vanadium has only recently become available in quantities large enough for thorough studies of its physical and mechanical properties […]

What Is Niobium Used For In Everyday Life?

0 Comment

What Is Niobium Used For In Everyday Life?  Niobium has a melting point of 4474℉, which is 256 degrees lower than that of molybdenum. The development of niobium metal and its alloys for elevated-temperature structural applications was started only a few years ago, but considerable progress has been made since then. One factor that has been […]
