Why Is There No Gasoline Without Rhenium? The previous article, Overview of Rhenium, introduces the discovery history of rhenium, physical and chemical properties, and magical rhenium effects. People have tried their best and they only have about 50 tons of rhenium a year. What are they used for? Why is there no gasoline without niobium? […]
Overview of the Refractory Metal Rhenium It is the latest natural element discovered by mankind; it is only one part per billion in the earth’s crust; it’s metal element is one of the necessary strategic reserves of various countries; its price is many times higher than that of gold and diamond… What is it? The […]
Technology is an essential cornerstone of modern weapons research and development. But in terms of importance, mineral resources are still above technology, which is because technology can be developed while it is really nothing can be done without materials. What are the top five strategic metals in the world? Titanium One metal known for its […]
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 […]
Only tungsten and carbon have higher melting points. Rhenium has good wear resistance and it can withstand arc corrosion. It is soluble in nitric and sulphuric acids. Applications for the metal include its use as an alloying element with tungsten. The rhenium powder is a light-gray metal powder made of agglomerated single crystals. Rhenium has […]
