Hafnium is inactive in nature and reacts with air to form oxide coverings, which are stable at room temperature, while powdered hafnium is prone to spontaneous combustion in air. Hafnium does not react with dilute hydrochloric acid, dilute sulfuric acid and strong alkali solutions, but is soluble in hydrofluoric acid and aqua regia. Hafnium is found in very small amounts 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 exotherm, etc.

Application

It is mainly used in the production of hafnium-based alloy materials, because hafnium has rapid heat absorption and heat release properties (1 times faster than zirconium and titanium), and can be used as structural materials for jet engines and missiles. The refractory nature of hafnium makes it useful as a blade for turbojet aircraft, used in freezing point pressure jet engines. It can also be used to manufacture valves, nozzles and other high-temperature parts.
