Rhenium Powder
Introduction
Rhenium Powder is a rare, high-performance material valued for its exceptional melting point, unique catalytic properties, and outstanding resistance to wear and creep. With a melting temperature of 3,180 °C, it is one of the highest of all elements, making it indispensable for aerospace, electronics, and advanced chemical processes.
Detailed Description
Rhenium Powder is produced through hydrogen reduction of ammonium perrhenate or other high-purity rhenium compounds. The resulting fine metallic powder typically exhibits high density, uniform particle size distribution, and excellent purity levels (from 99.9% to 99.999%).
Key characteristics include:
Ultra-high melting point: Ensures thermal stability in extreme environments.
High density (21.02 g/cm³): Provides strength for superalloys used in turbine blades and rocket engines.
Excellent catalytic activity: Promotes hydrogenation, reforming, and dehydrogenation reactions.
Good ductility: Unlike many refractory metals, rhenium can be processed into wires, foils, and compacts.
The powder form is especially suitable for powder metallurgy, additive manufacturing, and alloying applications, as it allows precise control over material composition and microstructure.
Applications
Rhenium Powder finds applications across advanced industries:
Aerospace & Defense: Strengthening nickel-based superalloys for jet engines and rocket propulsion systems.
Electronics: Used in filaments, electrical contacts, and thermocouples.
Catalysis: Platinum-rhenium catalysts in petrochemical refining (reforming of naphtha into high-octane gasoline).
Medical & Research: Targets for X-ray production, nuclear medicine, and high-temperature materials R&D.
Additive Manufacturing: 3D printing of high-temperature components for aerospace and energy industries.
