What is Rhenium?. A heavy rare metallic element that come into possession of either as gray powder or as a silver white hard materiel. The chemical element rhenium is classed as a transition metal. The element was brought to light in 1925 by Walter Noddack , Ida tacke and Otto berg..
Scene 4 (36s)
Uses and Significance of Rhenium. Rhenium is used with platinum as catalysts in the production of lead free, high octane gasoline. This metal is used in alloys for jet engines and in tungsten and molybdenum based alloys. It is used as Filaments for miss spectrographs. Rhenium is also used as an electrical contact Rocket thrusters for small satellites. Rhenium is also used to make thermistors..

THE FUTURE. Being a relatively ‘young’ element, researchers and developers still see great potential for rhenium in future applications. One of the most promising properties of rhenium alloys is their favorable biocompatibility, making them very attractive for the production of medical products. Specifically, molybdenum-rhenium alloys have performed better in implants than conventional titanium alloys. Additionally, researchers have examined the properties of rhenium diboride as a material for hard coatings and found that its hardness is almost equivalent to that of cubic boron nitride..
