In a free form, rhenium is not found, but gadolinite and molybdenite ores may contain a small amount of this metal. The world annual production is about 5 tons, and the proven reserves are estimated at 3,500 tons, mainly in the USA, Russia and Chile.
Rhenium is a silvery rare metal, very hard, resistant to corrosion. Due to its high melting point (3185 ° C) it is used in the production of rocket engines in the composition of alloys together with tungsten and molybdenum. These alloys are indispensable for heating threads and targets of X-ray machines. They are also used as electrical contacts. Renewable catalysts are extremely stable and are used for the hydrogenation of chemicals. Rhenium thermocouples can measure temperatures above 2000 ° C. In a platinum alloy, this metal is used as a catalyst in the production of high-octane gasoline. In an alloy with molybdenum, they are superconductors at a temperature of 10 K. Renium-nickel alloys are used to fabricate single-crystal turbine blades.

The toxicity of rhenium is not established. It is known, however, that it can cause irritation of the eyes and skin. A liquid containing rhenium can cause skin and eye burns. If inhaled, rhenium vapors may cause irritation of the respiratory tract, up to dizziness or suffocation. Evek GmbH offers to buy rhenium. Price from the manufacturer.
