HIGH-PURITY NIOBIUM POWDER FOR HIGH-TEMPERATURE SUPERCONDUCTORS | HIGH SPECIFIC SURFACE AREA REFRACTORY METAL NIOBIUM POWDER | DIRECT FACTORY SUPPLY

Our superconducting-alloy-grade high-purity metallic niobium powder is manufactured using advanced [Hydride-Dehydride (HDH) / Radio Frequency Plasma Spheroidization] technology. This product is distinguished by its high purity, high specific surface area, and ultra-low chemical impurities.

We apply strict control over interstitial elements—particularly oxygen (O), nitrogen (N), and hydrogen (H)—which are highly sensitive in superconducting materials. This ensures that superconducting alloys (such as Niobium-Titanium / NbTi and Niobium-Tin / Nb₃Sn) maintain zero electrical resistance and perfect diamagnetism (the Meissner effect) at cryogenic temperatures. It is the ideal raw material for cutting-edge fields including aerospace superconductivity, Magnetic Resonance Imaging (MRI), controlled nuclear fusion, and high-energy particle accelerators.

Standard Particle Sizes: Available in -100, -200, and -325 mesh, or customized to your exact specifications with controllable D50.

• Superconducting-Grade High Purity, Eliminating Microscopic Defects: Strict control over metallic impurities such as Ta, Fe, and Ni prevents magnetic impurities or secondary phase precipitation in the superconducting phase, ensuring the stability of the critical current density (Jc) and the upper critical magnetic field (Hc2).
• Extreme Oxygen Control, Ensuring Toughness & Ductility: Our proprietary vacuum degassing technology reduces interstitial elements like oxygen and nitrogen to ultra-low levels. During the subsequent multi-core wire drawing process for superconducting wires, this effectively prevents wire breakage and brittleness, significantly improving the manufacturing yield rate.
• High Specific Surface Area, Maximizing Alloying Efficiency: The unique micro-morphology provides a higher specific surface area. When mixed and smelted with metals like titanium and tin (or sintered via powder metallurgy), it ensures faster reaction rates and more uniform alloying, completely eliminating composition segregation.
• Direct Factory Supply, Dual Guarantee of Cost-Effectiveness & Supply Chain: Sourced directly from our factory with zero middlemen. We offer high batch stability, with every shipment accompanied by the original factory chemical composition and particle size test reports.

• Superconducting Wires & Magnets: Base matrix and additive powders for Niobium-Titanium (Nb-Ti) and Niobium-Tin (Nb₃Sn) superconducting wires.
• Frontier Research & Large-Scale Scientific Facilities: Superconducting RF cavities, Tokamak (artificial sun) superconducting magnets, and high-energy particle accelerators.
• Medical & Industrial Imaging: Manufacturing of superconducting coils for medical Magnetic Resonance Imaging (MRI).
• Special High-Temperature Alloys: Additives for high-strength refractory alloys used in aerospace engine nozzles and gas turbine blades.

• Standard Packaging: 1-2 kg per bag (aluminum foil vacuum-sealed), externally packed in steel or plastic drums (internally filled with argon gas for protection). Custom bulk packaging is available based on customer requirements.
• Storage Conditions: This product is highly susceptible to oxygen absorption and moisture. It must be stored in a sealed, dry, and cool environment under an inert gas atmosphere. Strictly prohibited from being stored together with flammable substances or acids/alkalis.
• Logistics & Shipping: We support domestic mainstream logistics and specialized hazardous materials express lines, ensuring strict integrity and zero damage during transit.

The performance metrics of this high-purity, superconducting-grade niobium powder have reached industry-leading standards. It is your premium choice for enhancing superconducting material performance and reducing the comprehensive wire breakage rate during the drawing process.
