Spherical Niobium Powder Application

Niobium is the lightest refractory metal. It has the characteristics of high melting point, high-temperature strength and specific strength, and no radioactivity. It is the preferred thermal protection material and structural material for aerospace engines. Radiofrequency plasma spheroidized niobium powder has the characteristics of high sphericity, good fluidity, high purity, large loose packing density, the full internal density of the particles, and no hollow powder. It is widely used in palladium materials, vacuum coating, thermal spraying, coating, cold spraying, and other fields.

Packing of Spherical Niobium Powder

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’Spherical Niobium Powder is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
