Hafnium Powder is a form of elemental hafnium in powder form. It’s available in 9 variations, with particle sizes ranging from 1 to 45 microns. Hafnium is a lustrous, silvery-gray transition metal that is corrosion resistant and chemically similar to zirconium. Hafnium powder is used in filaments, electrodes, semiconductor fabrication, and as a neutron absorber in nuclear control rods due to its high neutron absorption cross-section. With its refractory properties, Hafnium Powder is also used in superalloys for aerospace applications.
