Hafnium oxide

1、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 ℃

CAS:12055-23-1

 

2.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.
