Applications
Aerospace & High-Temperature Alloys: Used in nickel-based superalloys for jet engines, gas turbines, and rocket nozzles. High melting point and thermal stability improve creep resistance and oxidation performance.
Nuclear Applications: Ideal for control rods due to its strong neutron absorption. Compatible with zirconium alloys and corrosion-resistant for reactor core components and shielding.
Electronics & Thin Film Deposition: Utilized in semiconductor fabrication, especially high-k dielectrics like HfO₂ for CMOS devices. Powder serves as a precursor for sputtering targets, ALD, and CVD processes.
Plasma Cutting & Surface Coatings: Employed in plasma torch electrodes and used to improve thermal barrier coatings for aerospace and industrial parts.
Additive Manufacturing & Powder Metallurgy: Suitable for powder bed fusion, HIP, and MIM. Fine particle size supports excellent flow, packing density, and reactive sintering for complex, high-performance components.
