Spherical Niobium Powder 5-25µm

Powder properties

Morphology: Good sphericity, most particles are regular spherical, smooth surface, reducing the interaction between particles, reducing the tendency of agglomeration, making the powder more dispersible during use.

Particle size: The particle size distribution is relatively concentrated, and products with different particle size ranges can be obtained through process control, generally at the micron level, which can meet the requirements of niobium powder particle size in various application scenarios.

Purity: In the process of RF plasma spheroidization preparation, the introduction of impurities is effectively reduced, the purity is high, and the content of impurity elements (such as oxygen, carbon, nitrogen, etc.) is low, which ensures the quality and performance stability of niobium powder.

Density: It has a high loose density and tap density, and is relatively compact when stacked, which provides a good foundation for subsequent molding processing and is conducive to improving the density and performance of the product.

Flowability: Good sphericity makes spherical niobium powder have good flowability. During storage, transportation and processing, it can smoothly carry out transportation, filling and other operations, improving production efficiency.

Application fields

Superconducting materials: used to prepare superconducting alloys, such as niobium-titanium alloy, niobium-tin alloy, etc. These alloys are key materials for manufacturing superconducting magnets and are widely used in nuclear magnetic resonance imaging (MRI) equipment, particle accelerators and other fields.

Steel metallurgy: added to steel as an additive, it can refine the grains, improve the strength, toughness and fatigue resistance of steel, and is used to produce high-strength alloy steel, stainless steel, etc., and is used in construction, machinery manufacturing, automotive industry and other industries.

Electronic field: manufacturing electronic components, such as niobium capacitors, which have the advantages of small size, large capacitance and good stability, and are used in electronic products such as mobile phones, computers, and communication equipment.

Aerospace: manufacturing high-temperature alloy parts, using niobium's high melting point and good high-temperature strength, can be used for the hot end parts of aircraft engines, such as turbine blades, combustion chambers, etc.
