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, full internal density of the particles, and no hollow powder. It is widely used in palladium materials, vacuum coating, and thermal spraying, coating, cold spraying, and other fields.

Product packaging

Vacuum packaging, 1kg/bag, 2kg/bag; iron drum lined with plastic bag 25 kg/drum; special packaging is available according to user requirements.
