Hafnium (Hf) Pellets Evaporation Materials


General


Hafnium is a chemical element with symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals. Hafnium is used in filaments and electrodes. Some semiconductor fabrication processes use its oxide for integrated circuits at 45 nm and smaller feature lengths. Some superalloys used for special applications contain hafnium in combination with niobium, titanium, or tungsten. It has a density of 13.31 g/cc, a melting point of 2227°C, and a vapor pressure of 10-4 Torr at 3,090°C.
