Application of Spherical Rhenium Powder
Rhenium is used in aerospace for jet engine components and gas turbines due to its excellent thermal stability and oxidation resistance. In additive manufacturing, its spherical powder form ensures good flowability and precision in 3D printing complex metal parts. As a catalyst in petrochemical refining, rhenium resists deactivation at high temperatures while enhancing catalytic performance. In electronics and semiconductors, it is valued for its electrical properties, making it useful in high-temperature applications like filaments and contacts. Additionally, rhenium’s ability to withstand radiation and extreme temperatures makes it suitable for nuclear reactors.

Consolidation methods for spherical rhenium and rhenium alloys
- The development of high density spherical rhenium and spherical tungsten-rhenium powders has enabled the use of advanced consolidation techniques for the manufacture of refractory metal components. The investigated consolidation techniques are powder metal injection moulding (PIM) and vacuum plasma spraying (VPS); both produce net shape components. The required particle size distributions for these applications vary. VPS uses a large powder particle size (<44 μm) while PIM requires a fine particle size (<20 μm). The major advantages of spherical powders over traditional powders in plasma spraying are the high density of the powder particles and its good flow characteristics.
No, rhenium is not flammable. It is a refractory metal with a very high melting point (3,180°C) and excellent resistance to heat, oxidation, and corrosion. Rhenium is stable under normal conditions and does not easily ignite or burn. However, finely divided rhenium powder, like many other metals in powder form, can pose a risk of combustion or explosion when exposed to an open flame or oxidizing agents due to the increased surface area. In bulk form, though, it is not flammable.
Rhenium is exceptionally strong, especially at high temperatures. It has a high tensile strength of about 1,030 MPa at room temperature, and its strength remains stable even at elevated temperatures, making it ideal for use in superalloys and high-temperature applications like jet engines and gas turbines. Its high melting point (3,180°C) also contributes to its durability and resistance to deformation under extreme conditions.
