Nature:
Hafnium oxide is a non-toxic, tasteless white solid, insoluble in water, hydrochloric acid and nitric acid, soluble in concentrated sulfuric acid and hydrofluoric acid; The chemical property is inactive and has the characteristics of thin film: the light transmission range is ~ 220 ~ 12000Nm; Refractive index (250nm) ～ 2
15 (500nm) ～ 2, and high melting point, so it is widely used
