What Can Rhenium be Used For

0 Comment

Rhenium is classified as a scarce refractory metal. It has the second highest melting point of any of the metals and has 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 a vacuum or hydrogen atmosphere. Rhenium […]

Why is Vanadium a Transition Metal

0 Comment

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 the abundant refractory metals. Pure vanadium has only recently become available in quantities large enough for thorough studies of its physical and mechanical properties and for alloy […]

The List of Abundant Refractory Metals

0 Comment

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 “refractory metals” is used narrowly to […]

Top 10 Materials with Highest Melting Point in the World

0 Comment

Tantalum Hafnium Carbide Alloy (3990℃) Tantalum hafnium carbide alloy (Ta4HfC5) actually refers to tantalum and hafnium pentacarbonate compound, which has the highest melting point among known compounds. It can be considered to be composed of two binary compounds, tantalum carbide (melting point 3983 ℃) and hafnium carbide (melting point 3928℃). Tantalum hafnium carbide alloys are […]

What are Refractory Metals

0 Comment

Refractory metals are different. As a group they provide a number of unique characteristics – such as resistance to high heat, corrosion and wear – making them useful in a multitude of applications. The next time you climb into your automobile take note that you are surrounded by components which are made of refractory metals […]

Which Elements Have the Highest Melting Point

0 Comment

As we all know, 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. Niobium, molybdenum, tantalum, tungsten and rhenium are […]

Why is Molybdenum a Good Conductor of Electricity

0 Comment

High tech metals are called refractory metals in scientific terms, with a high melting point of 3500 degrees C. Tungsten, molybdenum, tantalum and niobium are refractory metals. The characteristics of these materials are not only high melting point, but also difficult to mine and process. Special process beyond traditional metallurgical method is required. Stanford Advanced […]
