Niobium Powder
Niobium powder refers to metallic niobium with a dark gray or gray black metallic powder appearance. It is a crucial rare and refractory metal powder that plays an indispensable role in high-tech fields, especially in superconductivity, electronics, and aerospace industries, due to its unique superconducting properties, corrosion resistance, and alloying ability. Niobium (Nb) and tantalum (Ta) are "twin" elements with extremely similar chemical properties, so many characteristics and applications of niobium powder are similar to those of tantalum powder, but each has its own emphasis. The performance of niobium powder is determined by its particle size, particle size distribution, purity (especially the content of interstitial elements), specific surface area, and particle morphology.
Physical Property:Appearance: Dark gray or gray black metal powder.
Melting point: Extremely high, reaching 2477 ° C, it is one of the important refractory metals.
Density: 8.57 g/cm ³ (block).
Superconductivity: Niobium is the element with the highest superconducting transition temperature (9.2 K) among all pure metals, which is one of its most significant characteristics.
Chemical Property:Excellent corrosion resistance: Similar to tantalum, its surface can form a dense oxide film and has excellent resistance to acid (including aqua regia) corrosion, but can be corroded by hydrofluoric acid and hot concentrated alkali. Its corrosion resistance is slightly lower than tantalum, but the cost is also much lower.
Inhalation performance: Niobium can absorb and fix various gases (such as H ₂, O ₂, N ₂), which is a property that requires special attention in the vacuum electronics industry and superconducting cavity manufacturing.
Dielectric properties: Its anodized film (niobium pentoxide, Nb ₂ O ₅) is also a good dielectric material and can be used to manufacture niobium electrolytic capacitors.
According to different shapes, niobium powder can be divided into spherical niobium powder and irregular niobium powder. According to the particle size, niobium powder can be divided into coarse niobium powder, medium niobium powder, fine niobium powder, extremely fine niobium powder, ultra-fine niobium powder and niobium nanopowder.
Niobium Powder Application
Niobium powder produced by FUSHEL has the characteristics of high purity, uniform particle size, spherical shape. It can be applied to the following situations:
Superconductivity
Niobium is a metal raw material with the highest critical temperature. Alloys made of niobium have a critical temperature of 18.5 to 21 degrees, which is the most important superconducting material at present.
Superalloy
Niobium can be used to produce nickel, chromium and iron base superalloys. These alloys can be used in jet engines, gas turbine engines, rocket components, turbochargers and heat-resistant combustion equipment.
Niobium based Alloy
Niobium alloy can be used in liquid rocket thruster nozzle, such as the main engine of Apollo lunar module. Apollo service module uses another niobium alloy. Because niobium is at 400 ° C will start to oxidize, so in order to prevent it from becoming brittle, it is necessary to apply a protective coating on its surface.
Medical Care
Niobium also plays an important role in surgical treatment. It can not only be used to make medical devices, but also is a good "biological adaptive material", because it has excellent corrosion resistance, does not interact with various liquid substances in the human body, and almost does not damage the biological tissues, and can adapt to any sterilization method, Therefore, it can be combined with organic tissue for a long time and remain innocuously in the human body.
Steel
Niobium, as a microalloying element, does not change the structure of iron, but combines with carbon, nitrogen and sulfur to change the microstructure of steel. The strengthening effect of Nb on steel is mainly fine grain strengthening and dispersion strengthening. NB can form stable carbides and carbonitrides with carbon and nitrogen in steel. It can also disperse carbides and form steel with fine crystallization.
Electric Porcelain
Lithium niobate is a kind of ferroelectric material, which is widely used in mobile phones, light modulators and surface acoustic wave equipment.
Spherical Niobium Powder
The spherical niobium powder produced by FUSHEL is produced by plasma spheroidization technology, which has the advantages of high sphericity and narrow particle size distribution. It is mainly used in 3D printing/additive manufacturing, thermal spraying, laser cladding, injection molding and other occasions. The details are as follows:
