Appearance and description：

Hafnium oxide is the main oxides of hafnium, it is the white odorless and tasteless crystal in normal circumstances.

Name: hafnium dioxide	Chemical formula: HfO2
Molecular weight: 210.6	Density: 9.68 g/cm3
Melting point : 2850 ℃	Boiling point: 5400 ℃

Product properties：

Hafnium oxide is a kind of non-toxic and tasteless white solid, not dissolve in water, hydrochloric acid and nitric acid, be soluble in concentrated sulfuric acid and hydrogen fluoride acid；They are chemically inert, with thin film properties: transparent range～220～12000nm；refractive index（250nm）～2.15 （500nm）～2， with high melting point, so it has a wide range of end-uses.

Application：

1) Raw materials for hafnium metal and its compounds;

2) Refractory materials, anti radioactive coatings, and special catalysts;

3) High strength glass coating.
