■ Specifications

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

Performance characteristics: 4N hafnium dioxide (99.99%-HfO2) has the characteristics of high purity (99.99%, GDMS detection data) and low iron (Fe) content.
