Rhenium is one of the transition elements which ranges from metals to metal like semi - conductors. This element forms unique super conducting alloys with molybdenum. It is non corrosive in sea water. Rhenium is used to make high tempature alloy steels. The radioisotope Rhenium - 187 is used as a standard to measure the age of the universe.
Rhenium ranges in color from silvery - white to gray to a black powder.
Rhenium is a dense , ductile metal with a high melting point. Rhenium is the seventy - eighth most common element on earth. It is found naturally in Molybdenite and columbite ones. Molybdenite one is found in Chile,as well as in the states of New Mexico,Utah,and Colorado. It is also obtained as a by - product of copper and molybdenite melting.
