RHENIUM - Rarer than goldIn the earth's crust, rhenium occurs even less frequently than gold. In its pure state, rhenium is a very hard, brilliant metal, similar to platinum, and can only be formed at red heat. Its melting point, 3,186°C, is among the highest of all metals. It has a boiling point of 5,596°C and a density of 21.03 g/cm³.
Primary application in superalloys and catalysts
Due to these unique properties, rhenium is indispensable in many key industries:
- In the production of gas turbine blades, rhenium is used as an alloy additive in superalloys; primarily to increase the thermal resistance of the turbine blades
- Platinum-rhenium catalysts are used in the production of lead-free, high octane petrol. In contrast to pure platinum catalysts, they have better regeneration capacity and are more efficient over the production run time
- In addition, rhenium is used for semi-finished and finished products, such as anode plates used in medical applications.
