Hafnium and Hafnium Alloy

Hafnium, symbol Hf, atomic number 72, atomic weight 178.49, belongs to group IVB in the periodic table. Hafnium is a shiny silver-gray transition metal with a density of 13.31g/cm³ (20℃), a melting point of 2233 ℃ (2506 K, 4051 °F), and a boiling point of 4603 °C (4876 K, 8317 °F). The dense metal hafnium is inactive and reacts with air to form an oxide coating. It is stable at room temperature, while powdered hafnium is easy to ignite spontaneously in the air. Hafnium does not react with dilute hydrochloric acid, dilute sulfuric acid, and strong alkaline solutions, but it is soluble in hydrofluoric acid and aqua regia. Hafnium is low in the earth's crust and often coexists with zirconium. Hafnium has the properties of high-temperature resistance, corrosion resistance, oxidation resistance, easy processing, rapid heat absorption, and heat release, and is used as atomic energy materials, alloy materials, high-temperature resistant materials, electronic materials, etc.
