Hafnium (Hf) is a rare, silvery-grey transition metal with a high density and a very high melting point of approximately 2233 °C. The element hafnium is valued for its exceptional temperature resistance, corrosion resistance and distinctive physical properties, making it suitable for demanding high-temperature, electronic and specialty applications.
One important property of hafnium metal is its strong affinity for oxygen. This results in the formation of a stable oxide layer that contributes to good corrosion resistance. Hafnium also retains useful properties at elevated temperatures, making it suitable for thermally stressed components and specialty materials.
Hafnium is used as a raw material for the production of hafnium alloys, hafnium compounds and hafnium oxide. Due to its particular nuclear properties, it also plays an important role in certain nuclear engineering applications. High-purity hafnium is additionally used in the semiconductor and electronics industries, high-temperature technology, aerospace applications and research and development.
