Product description
Hafnium dioxide is a non-toxic, odorless white solid, insoluble in water, hydrochloric acid and nitric acid, soluble in concentrated sulfuric acid and hydrofluoric acid; It has stable chemical properties, high melting point, excellent optical properties, especially the good light transmittance in the near ultraviolet to mid-infrared, high refractive index and excellent chemical stability. And it has become the first choice for high refractive index materials for high-power lasers.
Application areas:
1. The raw material of metal hafnium and its compounds, used in the nuclear industry;
2. Refractory materials, anti-radioactive coatings and special catalysts;
3. Infrared optical coating materials;
4. High temperature structural materials


Precautions: This product should be stored in a cool, dry room to avoid heavy pressure. It should not be exposed to the air during use, so as to avoid moisture absorption and agglomeration, which will affect the dispersion performance and use effect. Unused products should be sealed or stored in a vacuum after unpacking.
