Hafnium Oxide, HfO2

Product Information

Hafnium Oxide (CAS: 12055-23-1) is a kind of white powder, which is regarded as one of the most commonly used high-index coating materials for optical components. Thanks to a high refractive index and a wide region of low absorption from the near-UV to the mid-IR, hafnium oxide is the perfect material used for optical coatings. Indeed, thin deposits of hafnium oxide provide hard, scratch-free coatings for applications such as near-UV laser, anti-reflective, and dielectric mirrors.

Hafnium Oxide is a highly insoluble thermally stable Hafnium source suitable for glass, optic and ceramic applications. Hafnium oxide is an inert, off-white powder also known as hafnia with a high melting point, it is among the most common and stable hafnium compounds. Hafnium Oxide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Hafnium has the highest magnetic moment (10.6 µB) of any naturally occurring element and has been used to create the highest known magnetic fields as a pole piece or magnetic flux concentrator. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity.

Hafnium Oxide, HfO2 Properties (Theoretical)

Applications of Hafnium Oxide, HfO2

1. As the main chemical product of hafnium, it is usually used as an optical coating material. HfO2 has a relatively high melting point, a large absorption cross-section of hafnium atoms, a strong ability to capture neutrons, and particularly stable chemical properties, so it has great application value in the atomic energy industry.

2. It is the raw material for the production of metal hafnium and hafnium alloys.

3. Used as a refractory material, anti-radiation coating, and catalyst.

4. High-temperature structural materials
