Rhenium Applications The previous article, Overview of Rhenium, introduces the discovery history of rhenium (Re), 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? Aerospace field Because rhenium and other metals can be made into a […]
Molybdenum mining and processing technology have been improving since 1916, when Climax molybdenum was first mined near Leadville, Colo. At present, the main molybdenum mines in the world are distributed in the countries near the American continental divide, such as Canada, the United States, Mexico, Peru, Chile and China, and the CIS (Commonwealth of Independent […]
Rhenium has been discovered for almost a century, but it is still an unfamiliar element to most of us. It ranks 75th on the periodic table of the chemical elements and is the most recently discovered natural element. Rhenium is a silver-white metal with little natural content. Rhenium is less abundant in the earth’s crust […]
Space, once the arena of great power rivalry, now depends on international co-operation for its costly endeavor. The aerospace industry represents the economic, military and technological level of a country, and is also an important symbol of a country’s comprehensive national strength and national defense strength. Of course, the development of the aerospace industry requires […]
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 […]
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 […]
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 […]
