Rhenium powders
In 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. Due to these unique properties, rhenium is indispensable in many key industries such as aviation.

Ammonium perrhenate
For catalysts and rhenium metal
Ammonium perrhenate (APR) is a colorless powder that dissolves completely in water. At approx. 365 °C it decomposes into rhenium oxide (Re2O7), ammonia (NH3), and water (H2O) as a result of thermal decomposition.
Ammonium perrhenate can be used directly in the production of catalysts, e.g. for synthesizing platinum-rhenium catalysts used to increase the octane rating of gasoline.
In addition, it serves as a precursor material in the manufacture of rhenium metal powder and pellets, an important additive in superalloys. In a homogeneous mixture with the other components of the special alloys, rhenium metal powder is used in semi-finished and finished products, such as anode plates in medical applications.
Certified top quality delivers the best results
Ammonium perrhenate produced by Höganäs is characterized by a high degree of purity. We ensure the consistent, outstanding quality of our products as certified by our customers. As a result, our ammonium perrhenate meets the requirements of any industry, whether it is used as a catalyst or to manufacture special alloys or superalloys.
The complete solubility and highest degree of purity of our ammonium perrhenate is crucial for the quality of the catalysts: complete solubility results in a particularly uniform catalyst because the rhenium can be used to the fullest extent. Due to the high degree of purity, the catalyst is free of impurities that could affect its performance in its later use. In further processing to produce rhenium powder or pellets, ammonium perrhenate ensures consistency in reduction properties, which is crucial in preventing the formation of defective crystalline structures that could occur due to the remaining oxygen, for example. Because our ammonium perrhenate has such high degree of purity, the alloys are also nearly free of any possible element contamination.
Broad range of technical application support and recycling
Our service portfolio also includes comprehensive application technology support for product selection and process optimization as well as customer-oriented product modification and enhancement. To ensure a sustainable supply of raw materials, we offer rhenium recycling from used products, for example used catalysts or turbine blades and processing residues. Recycling is offered either by purchasing used materials or by reprocessing a certain rhenium product.
Perrhenic acid
Perrhenic acid is a strong acid that can be described as an aqueous solution ranging in color from colorless to pale yellow. It can be used directly in the production of catalysts, e.g. for synthesizing catalysts that contain rhenium and are used in the petrochemical industry.

Rhenium metal powder
The rhenium metal powder produced by Höganäs is a light-gray metal powder made of agglomerated single crystals. It features the highest degree of purity and consistent, certified product quality, which we guarantee.
Rhenium metal powder is used for semi-finished products, such as anode plates used in medical applications. Typically, it is first thoroughly mixed with other components of the special alloys.
High degree of chemical purity, consistent physical quality
Because the rhenium metal powder produced by Höganäs has a high degree of chemical purity, it can be used in the synthesis of special alloys with well-formed crystal structures. Thanks to its consistent physical quality - grain size distribution, tap density, specific surface area - it is perfect for mixing with other powders in a preliminary mixture from which a highly homogeneous semi-finished product is created in the sintering process.

Rhenium pellets
Used for turbine superalloys
The rhenium pellets produced by Höganäs are light-gray tablets sintered under hydrogen. They are approx. 4 mm thick and have a diameter of approx. 10 mm. They are used in the production of superalloys needed for high-pressure turbines in the aviation industry and industrial gas turbines.
A high degree of chemical purity for perfectly formed crystal structures
The rhenium pellets produced by Höganäs feature the highest degree of purity and consistent, certified product quality, which we guarantee. The high degree of chemical purity makes it possible to manufacture superalloys with perfectly formed crystal structures. The pellets’ solidity and uniform geometry makes it easy to accurately measure out exact quantities in foundry operations.
