Hafnium Oxide (HfO2) Description

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 (HfO2) Applications

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
