CAS 7440-58-6
:Hafnium
Description:
Hafnium is a transition metal with the chemical symbol Hf and the CAS number 7440-58-6. It is characterized by its high melting point, which is one of the highest among all elements, making it useful in high-temperature applications. Hafnium is silvery-gray in appearance and exhibits a metallic luster. It is known for its excellent corrosion resistance, particularly in acidic environments, due to the formation of a protective oxide layer. Hafnium has a relatively high density and is often used in nuclear reactors, as it has a strong ability to absorb neutrons. Additionally, it is utilized in the production of high-performance alloys and in the semiconductor industry for its properties as a dielectric material. Hafnium is typically found in zirconium minerals and is extracted through processes such as fractional crystallization. Its chemical behavior is similar to that of zirconium, and it forms various compounds, including hafnium oxide, which is significant in electronics and optics. Overall, hafnium's unique properties make it valuable in various advanced technological applications.
