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.
